Hi, I'm 21 and I had unprotected sex with my partner on aug 22 and he pulled out but I'm not sure if there was any precum in me and around aug 29 I had a small amount of spotting(not sure if its really spotting), nothing else after that until around sep 1st I've been having really bad lower back pain and a little cramps here and there and just today which is sep 6 I start getting morning sickness(not sure if its really morning sickness). My last period was on Aug 12 and so I'm expecting my next one on sep 12. I'm very concerned right now because as of right now I don't want to be pregnant yet. please share if theres any advice, I would really appreciate it. thank you.
