Severe cramping but not constant

Katelyn
Ok I posted earlier about cramping and constipation tmi I know but I haven't been constipated for awhile now and sti have the horrible cramping. It's not constant but comes and goes throughout the day. I'm going to take a hpt tomorrow because I think I may be pregnant but I'm not sure. Do you guys think I could be pregnant? Or could it be something much worse .
