I had sex on August 31. My partner never ejaculated but the condom broke. Of course I'm worried about precum. 5 Days later on september 5th I got my period and it lasted though september 9th. After the 9th I had light spotting for about 2 days after which isn't normal. I now know that I am not pregnant from that. On september 22 my boyfriend and I didn't have sex but we did get intimate. He did ejaculate and we were both naked so I don't really know the chances of getting pregnant that way. My period is now 2 days late and I know know if it's from my last love connection or if it's the bactrim antibiotic prescribed to me 2 weeks ago. Please help!
