I have been having weird feelings. Me and my partner have been having unprotected sex, only he pulls out when he feels he's about to come. We have been having sex since November and very frequently (about once a week). I had a period in Dec but before it came I had vaginal itching and usually I have really bad cramps the day my period comes but instead the day after it came I had a cold sweat and nausea, I ended up throwing up later that night. It was also shorter than usual and turned into a brown discharge. After that we still continued to have sex, and after we had sex that next time I spotted for three days very light but still scary. Lately I get nausea randomly, loss of appetite after I'm really hungry (nausea while eating), abdominal pains, and my breast are really tender but just a little sore. I haven't taken a pregnancy test because being that I know how I feel about my partner I know this could be hysterical but I'm not sure. My period isn't due until next week Friday but according to Google periods don't really matter when it comes to pregnancy sometimes... Do you think I'm pregnant?

'Thinking' is meaningless. Knowing is all that matters. Of course you can be pregnant, but not based on symptoms or anything you say. Just what you did - you had sex. Withdrawing isn't even a method of birth control. It has almost the same rate of pregnancy as not. Buy a few test kits. And get the pill or patch.
