So i am 17 and two saturdays ago, me and my boyfriend happened to have sec. It wasnt a plan of mine it just happened. Well he came on my *** and it kind of dripped down some but im 100% sure it didnt go into my vagina. Well my period should have shown up today but it didnt. Instead, for the past couple days i have had signs of my period but its not showing up. I am having slight cramps and bloating every one in a while and i also have been having some white discharge. I have had really tender breasts for a couple days too.. Is this signs of me being pregnant or could this just be my body being all complicated? I am really scared and i am hoping you girls/guys can possibly give me some advice or answers of some sort. Thank you.
