On and off throughout my pregnancy, I have experieinced very extreme cramps which feel a lot like diahrrea cramps - They feel like the only relief I'll get is if I go. But no matter how I try, I can't go, it continues to hurt and becomes agonizing. Its happened about 3 times...No gas, or other symptoms other then the current nausea. Has anyone expeireinced anything like this? It last maybe, 10 - 15 minutes at its most severe - nothing or any certain kinds of food make it worse, and I wouldnt say its gotten worse over time.
