Well last month, I lost my virginity. I've had sex three or four times and we used a condom. I am also a runner, (which can delay my period). He said he came but the condom didn't break. I haven't had my period... Which is weird. But when I normally have my period i dont have cramps. My boobs just hurt a little bit. Lately I've been having cramps and my boobs hurt really bad. Should I be worried? Help!!
