I've recently (about a week or so ago) started having sex with this new guy and we don't use condoms. I am on the three month birth control, and I am currently in the second month of my pack. I'll admit that I may miss a day but I take two the next when I remember. My last boyfriend did not precum so I didn't think much about it when the new guy did.
Lately I've noticed that when I orgasm, I have these slight cramp-like pains in my abdomen. They die down a few minutes after. I never orgasm during sex so that hasn't been a problem. But I read somewhere that this could be a sign of pregnancy. I am 18 and NOT ready for a child.
My questions are
1) What could this be a sign of?
and 2) How will I know if I'm pregnant if my next period isn't for two more months?
I also forgot to mention that I have smoked since I was 15 or 16.
Not a heavy drinker by any means.
