Begin by counting from the first day of your menstrual cycle, and continue until the LMP of your next period.
Now that you’ve gotten your baby bump, you’re probably wondering when you’re little munchkin will join you in this real world! Well, you can all put all the guesses to rest by estimating your baby’s arrival date. But before you go ahead and set the date for the big arrival, it is important that you have great insight into how this work and the different principles that apply, so you can use the best one to get as close as possible to the accurate delivery time.
Keeping track of your pregnancy due-date is one of the most important steps of your pregnancy, but if you do not know (most women don’t) when you ovulated or conceived, then our calc tool can help. The best calc will reveal your bundle of joy’s best estimated due-date (EDD) based on your last menstrual period (LMP).
To explain briefly, the LMP refers to the start date of your last menstrual cycle aka period, and knowing its date and duration can help you determine when your next period will occur, the time frame in which you are fertile and ovulating, and the approximate gestational age and due date of the fetus. The first day of a menstrual cycle (bleeding) is the most notable, because it basically serves as a tracking code for your upcoming ovulation and the length of the cycle.
Understanding this cycle and its respective stages aka fertility awareness methods (FAMs) is an effective way of tracking your ovulation in order to prevent pregnancy when family planning, or increasing your odds of conceiving during intercourse. Furthermore, this information can help your doctor to diagnose any issues related to early infertility.
If you aren’t sure of the exact date of your ovulation, you can use our ovulation calculator to determine the approximate first day of your period since this number is roughly 14 days from it. Another great reason to use our ovulation calc tool is because the chances of you getting pregnant are dramatically increased if you have intercourse on the same day or within three days leading up to ovulation.
The gestation period is the duration of your pregnancy measured in weeks, and is approximately 40 weeks from the day of conception. This period can be calculated using a pregnancy wheel, which uses your LMP to determine the number of weeks you are into your pregnancy, and the time your little munchkin will arrive. A pregnancy wheel is usually used by medical professionals and soon to be proud parents to highlight important landmarks of the pregnancy cycle.It can also help with scheduling of antenatal checks and sort out any issues related to fetal movement.
Most calculators use either the Naegele's rule or Mittendorf-Williams rule to determine your approximate due-date although both principles have their own set of advantages, the Naegele's rule is most commonly used by EDD calculator to predict your delivery date. As mentioned earlier, your gestational period lasts roughly 40 weeks after your first day of LMP, where each period cycle runs for 28 days or so, and ovulation occurs at day 14. The Naegele's rule calculation multiplies 40 weeks by 7 days per week, which equals 280 days, and then adds this number to the first date of your menstrual cycle (LMP).
Modern medical statistics however indicate that some women’s menstrual cycle may not be 28 days with ovulation occurring at day 14. This is when you can try the alternative Mittendorf-Williams method to figure out your delivery date. Even though this rule is proving to be much more accurate than the Naegele's rule, it offers a much more complex calculation process that takes into account several metrics including your race, height, weight, average luteal phase length and maternal age.
Our advanced tool asks you to enter your LMP, and the average days in your menstrual cycle (because there may be more than 28, and ovulation may not occur exactly on day 14) to give you the best estimated accurate delivery time.
Before using this however, you will have to know that you’re pregnant to begin with, so here are a few symptoms that may ring the alarm.
Tiredness is generally experienced during in the early stages of pregnancy, and you may also feel low levels of energy.
Owing to hormonal changes, your breasts may either feel fuller and heavier or tender, tingly or sore. This can be experienced as early as two weeks after getting pregnant (conception).
You may notice a small amount of bleeding or spotting aka implantation bleeding a bit earlier. It doesn’t last as long as your regular period, and the other difference between the two is that it is lighter in color.
Contrary to popular belief, this may happen at any time of the day or night, and may begin as early as two weeks after getting pregnant.
when you’re pregnant, your taste buds may appeal to certain foods, and generally takes place when there are accelerated hormonal changes.
Even though a pregnancy calculator will provide you with your estimated delivery date, medical research and statistics indicate that only 5 percent of women deliver on their exact due date. This is why a “Due Month” is a more accurate timeframe to go by because it can be either two weeks before or after the due date.
