Im 16 and thought there was a chance that i could be pregnant but i wasnt sure. i had unprotected sex about 4 weeks ago and i've experienced nausea, fatigue, headaches, sore breasts, frequent urination, weird feeling in tummy. but then it all stopped and i got what i thought was my period (monday morning) but it only lasted 2 1/2 days(till yesterday afternoon) and was lighter than normal. Then today we had sex again but used a condom and before we did I thought i was completely off my period because i no longer had vaginal bleeding but during intercourse i bled, but then later on today i'm like kind of spotting.So i'm really confused, and i'm not quite sure if its my period or theres a possibility that i'm pregnant? My boyfriend thought i should take a test but after i got what we both thought was my period we thought it was fine? Cause I read that you cant be pregnant and have a period, but spotting is normal? i don't know, can someone please help me?
