Wet underwear and clothing...

Loren
Im 33 weeks and yesterday and today i noticed while sitting down and the baby moving alot that once i got up to walk or move not only my underwear but also my clothing had wet spots... I have my MFM dr apt tuesday so i can ask then but im wondering if i should call my regular ob before then. I know its a warmer time of year than usual around here but i dont think being pregnant would make me sweat that much however i know some women have leaked urine and didnt know when it was happening and some have also leaked fluids... Its to the point im seriously about to start wearing a pad , i dont want wet spots on my clothing lol.... Any other moms having this problem?
