ive been asking alot of questions cause im due in 6 days and i feel my whole body is changing this is my first baby im 17 , my sister told me to do squats and ive been walking ALOT i did 20 squats and now my legs are really shaky and im getting small contractions not too bad i can tolerated pain pretty well , has shaky legs happened to anyone before labor or do you think it was probably just the squats i did ?
