You'll know when your getting real contractions!!! At first they feel like menstrual cramps and get worse and they are timeable apart evertime unlike Braxton hicks which is irregular
Had to comment I had my daughter at 37+3 :) but i never had one contraction! Went in for a check up and my dr. said i was 6 cm dilated and to meet him jn labor and delivery!! Good luck!!
the only thing i can say is that contractions are very painful where as to me braxton hicks are just uncomfortable. my contractions started in my back and lower abdomen like by my pelvis. im 37+3 too!!!! and i knew it was real when i could not stand it anymore!
