Babies

So I've had sex with my boyfriend and the condom broke but we realized before he came so it was just pre cum, and then like two weeks later we had sex in the shower without a condom and he didn't cum again it was just pre cum, I still haven't gotten my period and I'm like 13 days late. I took one pregnancy test (it was like $6.50 so they are sometimes unreliable?) and it said I wasn't pregnant but however I'm still late and over freaking about it help!!! Btw he didn't cum at all before we had sex
