My last period was feb 2 2016 and I make sex with my boyfriend last feb 25 is it possible that ill be pregnant?

The long and short of it is yes. Anytime you have sex, you are risking a pregnancy. Ovulation estimates and just that, estimates based on averages, and they can vary widely from woman to woman and even cycle to cycle.

Yes, while of course there are many reasons for a women being late, pregnancy is one of those options.

If you are more than 10 to 14 days late, you can do a pregnancy test
