I am 30 weeks, 5 days pregnant. Last night from 10PM until about 3AM I had strong contractions (cramping) about every 30 minutes (they were NOT Braxton Hicks contractions). I would often get chills after or during the contraction. Today I have felt better, just tired from lack of sleep last night, but I just feel sort of off . My temp is 99.5. Of note, I had a previous pre-term delivery at 35 weeks, 3 days. Should I go to urgent care and be seen? Or only if the contractions start up again?
