I'm 16 and female. On Jul 31 to aug 4th was my last period. My bf and i tryed to have sex 6 days before i knew I was supose to have my period. We didnt do it because it hurt me to much but he came in my mouth twice and fingered me before he got undresed so I don't think I could be pregnant but I'm worrying badly I told him he said he was sacred as well. But I traveled 1000 mile away for the summer and came back and hade my period in the car ride. I'm stressed about school. But I'm sacred bc it hurts to hug my knees and  to sit up when I lay down. I'm 8 days late as my period tracker says. I'm sacred someone help me...please
