I have been on an oral birth control since November 18, 2007. Three weeks later, Dec. 8, I had sex for the first time. That day my boyfriend and I had intercourse then decided we should stop before he came and get condoms- so we went out and got some. We had had sex twice with condoms but I was really worried about getting pregnant because I was new to sex and because. But Istarted my period two days early.

Since that period, we have had intercourse a few times but twice we didn't use a condom. He didn't ejaculate either time but I'm still worried. My breasts are sore but I sleep on my stomach and have sore breasts often.

What worries me the most is that after intercourse I get a feeling of pressure in my abdomen. It isn't really painful, it's kind of like a sour tummy after eating or something. But it happens every time. I don't know if I have some sort of infection or what.

Is my boyfriend thrusting too far inside me?

Could I be pregnant and just not have morning sickness?

I also have random aches all over. I have had mono twice, 4 years ago and last winter. It feels kind of like that.. But I'm just so worried my head is spinning
