When Should I See A Doctor For A Clinical Pregnancy Test
Most women who have a positive pregnancy test should wait a week or two before calling the Ob/Gyn office for a pregnancy blood test. We suggest waiting because the rate of early pregnancy loss is high, and its possible that it might have been a chemical pregnancy.
However, women with a history of ectopic pregnancy or current abdominal pain should call the doctor right away to be examined. Ectopic pregnancies implant outside of the uterus and produce hCG, resulting in positive pregnancy tests. However, these pregnancies can cause abdominal bleeding and prompt medical care is necessary. Women who have congenital heart defects or other chronic physical or mental health conditions should also see a doctor right away because treatment plans or medications might need to be altered to protect the woman and the fetus.
Advances in home pregnancy tests give women greater insight into whats going on in their bodies sooner than ever before. No matter what a womans childbearing plans might be, its essential to get quick, accurate results at home so she can plan her next steps accordingly.
How Do Pregnancy Tests Work
After sex, an egg is fertilized with sperm . The fertilized egg travels to the uterus and attaches into the uterine lining . Implantation occurs about 7-14 days after you have had sex, and it triggers your body to start producing the pregnancy hormone, hCG. Your hCG levels will double every 48-72 hours after implantation, and it is important to give those levels time to climb.
How Many Days After Missed Period Can Period Pregnancy Test Be Positive
Pregnancy tests check if you blood or urine has the human chorionic gonadotropin hormone which is released after a fertilized egg is implanted on the wall of the uterus. This process takes six days after fertilization in most cases. The level of hCG continues to increase throughout pregnancy and doubles after 2-3 days. To get a positive pregnancy test, most women will have to wait 5-10 days after their period was due. Some may detect pregnancy earlier becuase hCG accumulates at different rates for different women. The two major pregnancy tests are discussed below.
1. Urine Test
A woman can take a urine test at home or at her doctors office. She can take a home test a week after missing her period and then conduct another test with the doctor to confirm the results. The advantage of home pregnancy tests is that they are convenient, easy, quick and private. Urine test products come with clear instructions that any woman can follow. Following those instructions carefully gives accurate results. Heres how to do a urine test:
- Place the tests stick in the urine stream
- Dip the tests stick in a cup full of urine
- Use a dropper to transfer urine from a cup to another container.
After a few minutes you will see a + or symbol, one or two lines or color depending on the kit. Digital urine tests give pregnant or not pregnant results. Consult your doctor or the number given on the kit if you are unsure about the results.
2. Blood Test

Pcos And Pregnancy Tests
Menstrual irregularity is often due to an imbalance of hormones. Some women with PCOS can have a period that lasts three weeks. Others may not get a period for three months, never knowing when or if it will show up. Some women may get no periods whatsoever.
Only a small percentage of women with PCOS will have a regular menstrual cycle.
A woman with PCOS who is trying to get pregnant could face the problem of not knowing if she is pregnant or not. She and her partner could attempt to conceive for months, trying to have sex at the most likely time of ovulation, when an egg is released.
Then, one month, she may miss a period. Since she always has an irregular menstrual cycle, however, this may or may not mean she is pregnant.
She and her partner might get their hopes up, thinking she is pregnant. But then she could take a pregnancy test and have it be negative. This scenario can repeat month after month and be a frustrating, emotional experience.
Or, in another month, a home pregnancy test could finally have a positive result. Then, at her first OB/GYN appointment for her pregnancy, she may learn that she was already 10 weeks pregnant. This is because the previous results were wrong, something that is also common with PCOS.
How Early Can Home Pregnancy Tests Show Positive Results
In the Aerosmith song Sweet Emotion, Steven Tylers lyric the rabbit done died refers to the original way a pregnancy test was performed one that literally killed rabbits. Urine from a woman who thought she might be pregnant was injected into a rabbit, which would then be surgically opened so its ovaries could be inspected. If the woman was pregnant, the rabbits ovaries would undergo noticeable changes due to the hormone human chorionic gonadotropin that develops early in gestation. The rabbit unfortunately didnt survive.
Thankfully, pregnancy tests have evolved substantially since the 20th century. Women now have access to advanced tests that can detect a pregnancy days before a missed period. In fact, a CBS News article outlined the best home pregnancy tests according to research from Consumer Reports, based on ease of use, ease of reading results, and effectiveness. Many tests today are marketed as simple and effective, but getting accurate results comes down to when the test is taken.

The Pregnancy Test Cant Detect Pregnancy Hormones Because The Levels Are Too Low
It takes at least ten days after conception for your body to produce enough of the human chorionic gonadotropin pregnancy hormone for a home pregnancy test to detect .
There are several reasons hCG levels can be too low to register a positive result, and they include:
- You tested too early
Even if youve already missed your period, you can get a false-negative result. Its not common, but it could happen if ovulation occurred later in your cycle than usual.
For example, you usually ovulate on day fourteen of your cycle. But this month, you were under a lot of stress and ovulated on day twenty instead. So, if you became pregnant, it would have happened about six days later in your cycle than usual, which means you wont get a positive pregnancy test until six days later.
If you get a negative result and suspect youre pregnant, try testing again in a few days if you still dont get your period.
- Your urine was diluted
You can also get a false-negative result if your urine is too diluted when you take your pregnancy test. For this reason, its best to use first-morning urine or test after you havent had any fluids to drink for about six hours.
A rare phenomenon called the hook effect can also lead to a false-negative pregnancy test result . A hook effect occurs when hCG levels are so high that the pregnancy test cant read it.
Situations that could cause a false-negative pregnancy test due to a hook effect include:
Rare Causes Of A False Negative
In rare cases, an ectopic pregnancy can cause a false-negative test result. An ectopic pregnancy is when the embryo implants somewhere other than the uterus. This usually occurs in the fallopian tubes, but it can also happen elsewhere.
An ectopic pregnancy does not develop properly and will not become a viable fetus. The formation of the placenta is delayed which impedes the production of hCG. An ectopic pregnancy can be dangerous if it causes the fallopian tube to rupture.
If your period is late and you are experiencing severe pain, call your provider right away or go to the emergency room.
Ectopic pregnancies are rare, occurring in around 1 in 40 pregnancies. However, they can be fatal. Around 9% of pregnancy-related deaths are caused by an ectopic pregnancy.
Another rare cause of a false negative test is gestational trophoblastic disease , more commonly known as a molar pregnancy. GTD is a rare type of tumor that forms from a developing embryo. In less than 1 in 100 cases, a healthy baby can develop from a molar pregnancy. Usually, however, a molar pregnancy ends in miscarriage.
GTD causes extremely high levels of hCG. As mentioned above, elevated levels of hCG can throw off an at-home pregnancy test and give a negative result. While GTD is a tumor, its rarely cancerous. The treatment is usually having a D& C. If pregnancy hormone levels remain high, chemotherapy might be needed.

When To Call Your Healthcare Provider
If your period is two weeks late and you are still getting negative pregnancy tests, visit your gynecologist. They may do a pregnancy exam and blood test. Your healthcare provider can also help you recognize the early signs of pregnancy so you know when to take a pregnancy test or schedule an appointment.
Contact your healthcare provider immediately and/or go to the emergency room if you have a positive pregnancy test along with:
- Severe abdominal or pelvic pain
- Nausea or vomiting
- Dizziness or fainting
These may be signs of an ectopic pregnancy, in which a fertilized egg implants somewhere other than the uterus. This is an emergency that can be life-threatening and requires immediate medical care. The symptoms could also be the result of another medical problem that requires immediate attention.
Always trust your gut instincts. The sooner you are checked for pregnancy, the sooner you can know for sure and receive proper medical care and treatment.
Consulting with your healthcare provider before getting pregnant is important. This will prepare your body for a healthy pregnancy. Your healthcare provider can help you find ways to make your menstrual periods more regular, too.

Negative Pregnancy Tests While Pregnant
Many women can be misled by a negative pregnancy test when they are, in fact, pregnant. These tests, in general, arent as accurate as wed like to believe .
When you use a home pregnancy test, what its searching for is hCG, a hormone your body produces during pregnancy. For a positive test, the amount of hCG needs to be detectable, so if you havent produced enough, youll see a negative result.
Are There Any Medications That Can Change The Result Of My Pregnancy Test
For the most part, medications do not change your pregnancy test results. Antibiotics, birth control, alcohol and many other drugs do not impact your test results. The main reason for a false-negative is testing too early. You might also get a false-negative if you use a home test incorrectly. Its important to follow the directions on your test kit to make sure you get an accurate result.
However, fertility drugs are one exception. These medications can sometimes cause a false-positive on your pregnancy test. If youre taking fertility medications, reach out to your healthcare provider about your results to make sure they are accurate.

/5read On To Know More
Whether you want to get pregnant or do not want to get pregnant, when to take the pregnancy test is a question that bothers most of the women. If you are trying to conceive, you might be eager to take the test and if you have missed your period or witnessing signs of pregnancy then just want to confirm whether or not thats happened.
With over-the-counter pregnancy tests now, you do not have to wait long to know whether you are expecting or not. You just have to pee on the stick and within a few minutes, you will know the answer. But for accurate results, you have to go through the process at the right time. Taking the test too early might give you a false result even if you are pregnant.
Could My Medications Be The Culprit
In general, painkillers, antibiotics, or other forms of medication unrelated to fertility wont affect your hormone levels or delay ovulation. Although fertility medications can produce false positives, they rarely produce false negative results.
However, if you use birth control, blood pressure medications, or allergy relief meds, they could interfere in other ways. Some may change when you ovulate or create irregularities with your period, which can lead you to suspect pregnancy.
