Missing a period, especially if you always had regular menstrual periods, is a significant event, so naturally, the next question that follows is, "Am I pregnant?" Pregnant women have no menstrual period. But not every woman who misses her period is pregnant.

Could you be pregnant?

If you missed your period, answer these 4 questions:

  1. Am I trying to get pregnant?
  2. Have I had sex during my fertile days?
  3. Have I not used contraception?
  4. Did I ovulate?

If you answered "yes" to all questions, there is a high chance that you are pregnant. But only a positive pregnancy test will confirm your suspicion.   

When will a pregnancy test appear positive?

If you are trying to get pregnant and you miss a period, you are naturally excited, yet there is no way to know for sure until you take a pregnancy test. However, there are several symptoms that are suggestive of pregnancy, including breast tenderness, nausea, and bloating. Keep in mind, these can also be premenstrual signs.

How many weeks am I pregnant from my last period?

Wondering how many weeks pregnant you are right now? Well, you first must know when your last period was in order to find out how many weeks you are right now. Calculating an accurate due date is an important first step in pregnancy. The calculation of the estimated due date (EDD) is based on the day of the date of ovulation and fertilization. The EDD can be calculated by adding 266 days to the day of ovulation/fertilization.

What is the last menstrual period (LMP)?

The LMP is the date of the first day of the last menstrual period you had before conceiving. It is the first day that your last menstrual cycle begins when you see bright red blood, not just a little brown spotting. You should keep track of your LMP each month, either with an online calculator or just by recording it on a calendar each month. That is the date you use when entering the LMP on an online period calculator.

Whether you are trying to get pregnant or not trying to get pregnant, keeping track of your menstrual periods is vital. Besides pregnancy, missing a menstrual period could also be a sign of other issues like missed ovulation.

Why would I have a late period?

Having a late menstrual period is among the first signs and symptoms of pregnancy. Other early pregnancy signs include breast tenderness, nausea, fatigue, and frequent urination.

Just enter the first day of your last menstrual period and the average number of days of your menstrual cycle above to calculate whether your next menstrual period is late or see if you might be pregnant!
