How Do You Estimate Baby Due Date Using Conception Date Calculator
If you are keeping a track on your ovulation and know the fertilization date, you can estimate the due date based on the date of conception. The estimated due date, in this case, will be 38 weeks from the date of conception. Only a few women can accurately track the ovulation days and can guess when they have conceived. But, the calculations can go wrong as you may not conceive on the same day of the intercourse. The sperm can live up to five days, and the ovum for up to 24 hours after being released. In short, there is only a six-day fertile window where you can get pregnant.
In cases of in-vitro fertilization, the date of conception would be precise.

Could My Due Date Change
The actual date the sperm and egg join is almost never known for sure. Your provider will likely recommend that you have an ultrasound once or twice in the first half of your pregnancy to make sure your due date is correct. The ultrasound can measure the size of your baby and use that information to figure out your due date. Your provider will likely recommend you have an ultrasound during your first trimester if you are not sure of the day your last period started, you had spotting or an abnormal period, you have irregular periods, or your providers findings on your exam do not match the due date based on your last menstrual period. The due date based on a first trimester ultrasound is usually the most accurate . The ultrasound due date will be used if there is more than a week or so difference between the due date based on the ultrasound and the due date based on your period.

Cervical Mucus Your cervical mucus changes when you ovulate. Cervical mucus during the first few days after your menstrual cycle will be dry. Your cervical mucus will begin to increase. As you approach ovulation, the cervical mucus will be plentiful, slippery, clear, and stretchy. Many women compare the consistency to that of egg whites.

Some people think the menstrual cycle and a period are the same thing.
A period is when you bleed .
A menstrual cycle starts on the day when a period starts and ends the day before the next period. A cycles length is considered normal if its between 21 and 35 days. They can vary between women and from one cycle to the next.
- Working out your average menstrual cycle length
If your menstrual cycles are different lengths you can work out your average cycle length.
The number of days in a womans menstrual cycle can vary month to month. Periods are not always regular. It can be useful to work out an average cycle length, based on the length of three menstrual cycles, to estimate when youre most likely to be ovulating.
If you add the number of days in three cycles and divide the total number by three, it gives you your average cycle length.
Example
Sarah tracked her last three menstrual cycles by counting the time from the first day of one period, to the day before the next period.
Cycle 1 was 28 days Cycle 2 was 32 days Cycle 3 was 27 days
28 + 32 + 27 = 87

Other Ways To Find Your Most Fertile Days
There are other ways to identify when youre ovulating. Pay attention to your body and youll see signs that ovulation is imminent. Your cervical mucus changes as you approach ovulation. Right before your egg is released, youll notice a change in the mucus discharge in your vagina. It will be clear, slippery, and appear like the white of an egg. This indicates a highly optimal time to conceive.
Another way to determine when you are ovulating is by charting your basal body temperature using a basal thermometer. This method is not as reliable as the OPKs and therefore its use is usually not recommended any longer.
Are Your Cycles Truly Irregular
An irregular period is defined as a menstrual cycle that is either shorter than 21 days or longer than 36 days. Your cycle may also be considered irregular if it varies significantly from month to month. For example, if one month your cycle is 23 days, and another it’s 35, your cycles would be considered irregular.
Research has found that variations in cycle length are associated more strongly with infertility than just having a shorter or longer regular cycle. In other words, if your cycles tend to be slightly longer than the normal range, but they are consistently that length, you may be less likely to experience fertility problems than someone whose cycles vary significantly but the length falls within the norm.
If your cycles are off by a day or two from month to month, you dont need to worry. Its when the variations are longerfive or more daysthat you may face fertility difficulties.
An occasional irregular cycle is also normal. Stress or illness can delay ovulation or menstruation, causing your cycle to be longer, and sometimes shorter, than usual. If you have just one or two of these “off” periods a year, you don’t need to worry. However, if your cycles are frequently irregularor you go quite a long time between menstrual cyclesyou should see your doctor for an evaluation.
