Last night around 4 am I got really bad cramps and my entire belly got hard. After 5 minutes they went away. This morning I woke up and my belly was sore and now Im getting minor cramping but still hurts. In 32 weeks pregnant. Should I go to the hospital? Update: I went to the hospital Thankfully everything is okay. I might have a bladder infection. I have to call my OB on Wednesday to get the results.
