Ive been cramping on my left sife for 10 mins and doesnt seem to be going away. Im 34+4 and havent had this happen until now. First started off small cramps but didnt really think to much of it until it started hurting really bad now its still hurting but not as bad but still hurts. Could it be a sign of labor?
