HELP! I can't be pregnant :(

Zoe
Well crap. I'm soooo scared right now. I recently split from my ex a couple of weeks ago, and now I'm scared I'm pregnant. I've been skipping my period on the pill, so I have no idea if I'm late or not. We had unprotected sex and yes he came in me. I take my pill daily but I get forgetful and usually it ends up being at different times, sometimes in the morning, sometime in the afternoon.
But! I've been doing some reading. Here's my details -  My cervix feels very low and soft! And my discharge is milky white. I've had pains in the stomach, been pooping A LOT, and I just have this gut feeling (hah!) that I might be.
I'm sooo worried. I can't be pregnant, I just can't. My ex was very abusive and I want nothing to do with him, and now is not a good time in my life. 
I'm so scared, if I'm pregnant I don't know what I'll do. :( 
Ladies, what do you think? What's my chances? Please help.
