I was at the point last night that I was going to get checked out but luckily the pain started to subside, it was such a relief. I was in so much pain I was feeling sick. Anyway I had a good night sleep but woke up this morning with a rumbly, windy feeling stomach again, feeling a bit nauseated and light cramps back in my right side. Who knows what caused last nights episode! But I refuse to take a HPT until at least for another week, maybe I've just got a stomach bug.
You need to call your doctor! "Severe" stomach cramping is not normal and needs to be addressed.
