I stayed home from work today to go to the doctors... I felt cramping all night. They did a test for a urinary tract infection and for preterm labor both came back negative. She told me just to beef up on my water intake. I do drink A LOT of fluids though so I didn't think it was that. I did some research online and found that around my time (6 months) you can feel something called Round ligament pain.... Which causes sharp pains and a low dull cramping.
