Blood Test Result Timetable
Blood tests are able to detect a smaller amount of hCG and they can detect it slightly earlier than standard at-home pregnancy tests, usually nine to 12 days after conception. Blood test results are usually available the same day or within a day.
Blood tests aren’t often done to detect pregnancy because they are expensive and at-home urine tests are quite accurate and sensitive. However, people who are undergoing fertility treatments may have blood tests as part of their care.
Can You Take A Pregnancy Test While On Your Period
Whether you have been trying for months to conceive or dont feel ready to have a child yet, if you think you might be pregnant its likely to bring out all the emotions. Even waiting one day to find out can seem like an eternity.
Luckily, your corner drugstore or local grocery should have you covered with pregnancy tests you can take at home ASAP. A quick trip to the bathroom, a few minutes of waiting, and the answer will display before your eyes.
But how trustworthy are those results? And what if youre bleeding or seem to be on your period, will that ruin the test results?
Food Cravings And Aversions
PMS: When you have PMS, youll likely notice that your eating habits change. You may crave chocolate, carbohydrates, sugars, sweets, or salty foods. Or you may have a ravenous appetite. These cravings dont happen to the same extent when youre pregnant.
Pregnancy: You may have highly specific cravings, and you may be totally uninterested in other foods. You may also have an aversion to certain smells and tastes, even ones you once liked. These effects can last throughout pregnancy.
You could also have pica, in which you compulsively eat items that have no nutritional value, such as ice, dirt, dried paint flakes, or pieces of metal. If you have cravings for nonfood items, talk to your doctor right away.

Dont Read The Results Too Early
Likewise, avoid reading your pregnancy test results too early. As your urine travels through the test indicator window, it might look like the results are showing, but the test needs time to completely work. Follow the testâs instructions as closely as possible and avoid checking on the results too early. If needed, set a timer to let you know, according to the instructions, when the results are ready.
What If You Have A 28
The average menstrual cycle is 28 days, with the first day of menstruation as cycle day 1.
Most periods last two to seven days. Pregnancy is uncommon during this time, because your peak fertility window is still about a week or so away.
Around days 6 to 14 of your cycle, your body will start releasing follicle-stimulating hormone .
This helps develop an egg inside your ovary. Your body will also begin rebuilding the endometrial lining in your uterus.
Pregnancy is slightly more likely during this time. Sperm can live up to five days inside the body, so it could still be present when the egg matures.
Once the egg is mature, your body will release lutenizing hormone , triggering the eggs release from your ovary .
Ovulation usually occurs around cycle day 14. Pregnancy is likely on ovulation day.
That said, ovulation doesnt always happen like clockwork. It can occur anywhere from four days before to four days after the midpoint of your menstrual cycle.
The bottom Line
If you ovulate later in your cycle or start your period sooner than usual, you could become pregnant if you have sex in the days leading up to your period.
Lots of people dont have 28-day cycles. Some have cycles as short as 21 days and others as long as 35 days.
In fact, in one study , only about 30 percent of participants had their fertile window fall within days 10 to 17 of their cycle. Only 10 percent had ovulation fall exactly 14 days before their next period.
You can do this a number of ways, including:

So When Is Pregnancy Most Likely
The only time you can get pregnant is during your fertile window.
An egg only lives for about 24 hours after being released from your ovary, and sperm can only live for up to five days inside the body.
That means you can only get pregnant if you have sex:
- in the four to five days leading up to ovulation
- on the day of ovulation
- on the day after ovulation
If youre looking to conceive, the best time to have sex is right before ovulation. This will give sperm time to reach the fallopian tube and meet the egg there.
After that, if no sperm has fertilized the egg, it will dissolve. You wont be able to get pregnant until your cycle restarts.
Whats The Difference Between Home Pregnancy Tests And The Tests At A Doctors Office
The main hormone you are testing for is human chorionic gonadotropin , which is detectable in blood or urine. The concentration of hCG doubles every 29 to 53 hours during the first 30 days after implantation of a viable, intrauterine pregnancy a slower rise in concentration of hCG is suggestive of an abnormal pregnancy or early miscarriage .
The âpee on a stickâ type of home test measures whether your hCG passes a threshold amount, and gives you a positive or negative answer. These tests often give a negative result if the test is done too early after a missed period.
If you do a home pregnancy test and get a negative resultâââbut you still donât get your period one week laterâââthen itâs a good idea to follow-up with another test.
Healthcare providers often offer both urine tests and blood tests for hCG. The urine test offered is very similar to a home pregnancy test, but the results tend to be more accurate due to reduced error. A blood test will give you a precise count of your hCG levels. Because the blood needs to be analyzed by a lab, you will need to wait longer to find out the results.

What Causes Pregnancy Fatigue
When you first become pregnant, your body immediately begins to undergo major changes. These physiologic changes in the body are what contribute to early pregnancy fatigue, says Dr. Biegner. Some of the changes during early pregnancy that may lead to an increase in fatigue include:
- Increase in hormones like progesterone
- Increase in blood volume to help support a developing baby and placenta
- Low blood sugar
- Sleep disturbances
The fatigue you experience in those early weeks of pregnancy may disappear as you enter your second trimester, but Dr. Biegner says to expect it to return as you enter the final weeks before delivery. Some women will experience fatigue in the third trimester as well, she explains. This can be caused by the following:
- Carrying a growing baby is more work for the body and may cause fatigue
- Multiple bathroom trips that disrupt a good nights sleep
- Difficulty sleeping due to inability to find a comfortable position
What Are Some Less Common Signs Of Early Pregnancy
There are some additional signs of early pregnancy that arent as common. Just like with the most common symptoms, these signs of pregnancy may or may not happen. Its important to remember that everyone is different and experiences signs of pregnancy differently.
Less common signs of early pregnancy can include:

A urine pregnancy test looks for a hormone called Human Chorionic Gonadotropin that is found in the urine during pregnancy. Having your period during the test should not interfere with the accuracy of these results. Within about 2 weeks after conception, there is enough of this hormone to show up in the urine.

Genetic counseling can be beneficial if you are at risk for certain genetic diseases. This type of counseling involves taking an extensive medical history and assessing the health of you, your partner, and your respective families.

When To See Your Doctor
Although home tests can detect a pregnancy, it gives no information as to viability. Its important to make an appointment with your doctor to confirm your pregnancy and to detect a fetal heart rate through an ultrasound . If you have a positive pregnancy test, your obstetrician can provide information about warning signs of an abnormal or worrisome pregnancy and can advise you on when to make an appointment to confirm your pregnancy.
Is It Possible To Get A False Positive Pregnancy Test Result
Yes, but this is rare. A positive result can also be caused by:
Pregnancy loss very soon after implantation
hCG secretion from a tumor
Pituitary hCG secretion, typically in people going through perimenopause
Interference from hCG administered as part of infertility treatment. If youâve had an injection of hCG, this should be cleared from your system after two weeks.
Medications do not cause false positive pregnancy tests, unless the medication contains hCG or, rarely, certain antibodies . If you think your medication might be interfering with pregnancy test results, talk with your healthcare provider.

This doesnt mean you cant take a pregnancy test later in the day. It just means that youre more likely to get a false-negative, especially if youve been drinking a lot of water. Its easy to forget in the morning, so it might be helpful to leave yourself a note the night before. You can close the lid of the toilet and leave a note there to remind yourself.
What if you have an unconventional sleep schedule and cant test your urine first thing in the morning? You can increase the level of hCG in your urine by not using the bathroom for at least four hours.
Before taking a pregnancy test, dont drink more water than you normally would. Drinking a lot of water can dilute your urine and affect the result of your test.
If you got a negative result but still think you might be pregnant, take the test again after several days. False positives and false negatives are rare, but they do happen. Repeating a test can also be a good idea.

Whats Next If The Results Are Positive
Your next steps depend on two things: whether youre pregnant and whether or not you planned to get pregnant.
If your test results are positive and youve been planning to have a baby, take another test to make sure youre pregnant. Then, see your doctor before you reach the 8-week mark. You can ask them about prenatal care options or specialists who can help guide you through your pregnancy. Ask your doctor about any changes you need to make to your lifestyle, medications, or diet to keep yourself and your baby healthy for the next nine months.
If your test results are positive but you didnt plan to get pregnant, ask your doctor about available options, including:
- carrying the pregnancy to term for adoption
- what to do if you want to continue your pregnancy
You can also receive help from a clinic or health center that specializes in reproductive health and child care, like Planned Parenthood.
Dont Let The Test Sit For Too Long
There is a time limit involved in reading an at-home pregnancy testâif you read the test outside the window of time outlined in the instructions, you could end up with inaccurate results.
Most non-digital tests show lines to indicate the presence of hCG in the urine. One line will be a control line that shows up no matter what, and the second line typically indicates a pregnancy. If your test is negative, there is a chance you may still see a faint, colorless evaporation line that appears as the urine dries. If you’re not familiar with evaporation lines, you might see this line and think you’re pregnant.
Avoid letting the test sit too long, otherwise you may read an evaporation line and think you are pregnant.

How Accurate Are Home Pregnancy Tests
Most home pregnancy tests claim to be up to 99% accurate. But the accuracy depends on:
- How you use them. Be sure to check the expiration date and follow the instructions. Wait up to 10 minutes after taking the test to check the results window. Research suggests that waiting 10 minutes will give the most accurate result.
- When you use them. The amount of hCG or pregnancy hormone in your urine increases with time. The earlier you take the test, the harder it is for the test to detect the hCG. Most home pregnancy tests can accurately detect pregnancy after a missed period. Also, testing your urine first thing in the morning can boost the accuracy.
- Who uses them. Each woman ovulates at a different time in her menstrual cycle. Plus, the fertilized egg can implant in a woman’s uterus at different times. Your body makes hCG after implantation occurs. In up to 10% of women, implantation does not occur until after the first day of a missed period. This means home pregnancy tests can be accurate as soon as 1 day after a missed period for some women but not for others.
- The brand of test. Some home pregnancy tests are more sensitive than others. For that reason, some tests are better than others at detecting hCG early on. Talk to your pharmacist about which brand may be best for you.
