my gf's last period came april 16 and ended april 22. We had sex for the first time on the 23rd and the last time on May 13. We used a condom and i wasn't close to orgasm and we stopped after i made her orgasm. The second time I noticed precum on the inside of the condom towards the base and i'm afraid it may have leaked. I did orgasm that morning but i also urinated many times before sex. She took 3 pregnancy tests, the latest one being june 7th, and she had been 2 weeks late at that time, and it had also been over 20 days since the last time we had sex. We're both extremely worried she's pregnant despite the tests. She has not experienced any symptoms
