So nervous!!! Need advice! Am I pregnant?

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! :/

It's possible. You could have ovulated the 24th or 25th and then you can get pregnant with the pre-cum. On the other hand if you ovulated later then your period would be a little later as well. Wait till the morning and use first morning pee (your hormones will be at a higher concentration then and a home pregnancy test will be most accurate). You should be able to get accurate results by now.
You know this, but if you don't want to get pregnant and don't always use a condom with any penetration then your playing with fire. You should look into different types of birth control.
GL!

You might be able to take an EPT to see.

Thank you ladies! I just took a test and thankfully got a negative. Learned my lesson! :)
