A couple months ago I became sexually active. After my first time I went through a little spell of paranoia where I thought I was pregnant (even though we used a condom and I got my period 2 weeks later). But anyway I've been reading posts on these boards for a while now and there's one thing that really really scares the heck out of me - women who get pregnant, have no signs, still bleed, and don't even realize that they are until months later.

I'm just wondering how normal is that? aside from medical tests, how do women know that they're pregnant? I've been having some things that could be signs of pregnancy (mainly, sore breasts and nausea)...though I just attributed them to birth control pills, which I started about 2 months ago. Is there any chance I could be wrong?

Tell me about your experiences. All advice is appreciated.
