I was on my period Dec 26, and on the 28th my boyfriend & I had sex. We were kissing for about 30 minutes, he precame there a good bit, which I was aware of. Then after a while I went to get a condom and when I put it on him I accidentally put it on him backwards, I quickly realized and flipped it over before I could unroll it. My period app says that I was fertile Dec 27 - Dec 31, Ovulated Jan 1st, fertile again Jan 2 - Jan 6. (Everything happened on the 28th). I'm just scared about being pregnant due to the amount of precum that may had been on the condom. He said he urinated before any of this happened. Also, is there a large number of people that you know of that have had this accident before? And did they get pregnant or were they fine? Today is Jan 14, and I am expecting my period on Jan 17. Thank you.
