I think I'm having mild contractions, is this normal for 33.5 weeks? I have told my OB about it and she just said if they get worse, more frequent, or if I start bleeding, then I should call her. My next appt is on monday right when I hit 34 weeks, and I know they normally start checking your cervix at 36 weeks, but man I have having period like cramps in my lower belly and back for 3 days now, so I wonder if this is very early contractions...
