I'm 7 weeks pregnant and find myself overheating during the night, this is causing really severe stomach pains. The only thing I can compare it to is when you get sunstroke and you get "the runs", it's that type of stomach pain that makes you want to throw up at the same time but nothing comes out. Is this normal? We had an early scan and definitely not ectopic. I think I may be a bit constipated too
