belly pain

I'm about 9-10 weeks and my boobe soreness goes away and comes back, but I still have Nasuea and vomiting I just have to try and keep it under control. Yesterday and a little today I've been having this weird stomach pain that was in believable through out the day. I figured I had to poop so I tried and I couldn't because the zofran makes me constipated a little but the pain scared me into think something is wrong. I lost my last angle around this time in August and I don't want to loose another one. I think I should be okay I finally was able to use poop today and kinda feel better. Still stressed but going to relax now. The belly pain felt like a burning but also like a cramp I have had no blood what so ever since this pregnancy began. The pain would last about 10 15 seconds and then go away for about 30 40 minuets it make me feel so sick my tummy felt really tight. I'm pretty sure a lot of ladie have had this. It just freaked me out a little bit
