So i am 18 and i had anal sex about a month ago with a condom, and before he put the condom on we were cuddling and he might have gotten precum on my butt. Around a week later after this i started to get some weird pink and brownish discharge only when i wiped which lasted only 3 days. I was really scared, I didn't get my period on time so I took a pregnancy test 2 days after I was supposed to get it, IT WAS NEGATIVE. I just got my period yesterday the 19th. Can i still be pregnant? I know this may be stupid but i have really bad anxiety about this. Thank you.
