Question
I had my period on April 27th. Now the pregnancy test is positive. How many weeks pregnant am I, and when is my expected due date? My regular period is about 30 days.
Answer
Pregnancy weeks are calculated from the first day of the last menstrual period, totaling 40 weeks, approximately 280 days. If the last menstrual period was on April 27th and the menstrual cycle is about 30 days, then you are 42 days pregnant, with an expected due date around February 3rd, 2012.
