Pregnancy Calculator

Once you confirm your pregnancy with a test you can think about what you would like to do. You can decide to terminate or continue the pregnancy, and, if you want to continue, you can choose to parent or give the baby up for adoption.

You know what is best for you! Whatever you decide, safe2choose will always support your choice.

The easiest way to calculate your weeks of pregnancy is by counting from the first day of your last menstrual period. This means the date in which you actually had your last period. Some women start counting from the day they were supposed to get their period and did not, but this is incorrect. Other women start counting from the day they had sexual intercourse or the day they believe they became pregnant which is not accurate either as a pregnancy does not start the same day of sexual intercourse. If you count how many weeks and days have passed since you had your last menstrual period, that is how many weeks/days you are pregnant.

If you need support to calculate your weeks of pregnancy, enter here the first day of your last menstrual period.

If you do not keep track of your period or you cannot remember the last time you had it, you can think what you were doing when you last got it. Where were you? Who were you with? This sometimes helps you to remember the date when your last period occurred.

Another way to calculate the time of pregnancy is with an ultrasound. This can be very helpful if you do not remember your last menstrual period or you have irregular menstrual cycles. There can be a small difference between the calculation with your last menstrual period and with the ultrasound. This is usually normal as neither technique is exact, but they are the most accurate ways to estimate the weeks of pregnancy you have.

Calculating your weeks of pregnancy is important regardless if you decide to terminate or continue the pregnancy. If you decide to end the pregnancy, the weeks of pregnancy will help to determine which options of abortion methods are best for you.

If you decide to continue the pregnancy this will help your midwife or doctor to know if the pregnancy is evolving normally. Consider a pregnancy usually lasts around 38 to 42 weeks from the first day of your last menstrual period.
