So I keep track of all my periods and my last period was on 8/8, according to my period tracker app I was fertile from 8/17- 8/23. And my ovulation day was said to be on 8/22. I had sex with my boyfriend the night of 8/24 and on 8/25, which would be two days after ovulation. I've read that an egg lasts up to 24 hours. My problem is that my boyfriend didn't use a condom for like the first two minutes and then put one on and finished in it sometime later. This also happened the next day, but he always had a condom on when he cummed. I'm nervous because I was expecting my period (which is always on time) and I'm going on being two days late. I will probably be taking a pregnancy test later today. If its been 13 days after intercourse would a pregnancy test today tell me accurately if I'm pregnant or not? And do you think theres a chance I could be pregnant? Ive been so stressed out these last few days. Please help! :/
