Am I pregnant? Please help!!!!?

I had my period June 13th to 19th. I had unprotected sex the 22nd and 23rd. Twice each night. He precame in me and possibly came in me. (he isn't sure). I've been wondering if I'm pregnant. I thought I had some symptoms last week but I think it was just my in my head. But today I noticed I'd be starving but every time I ate I could only eat a little then I'd feel full and then like an hour later I'd be hungry again. I feel really bloated today too. And just now I felt like I needed to go poop, I tried but nothing happend, and now I have REALLY bad cramps. Like the worst cramps of my life and it hurts to move or do anything. I never get cramps except the first day or two of my period. My period isn't do for another week and I already ovulated. Could this be my uterus getting bigger? Cause thTs what it feel like it could be. It's been 10 days since the sex. Also my cervix is high and soft and closed.
