hi, i am 39 weeks pregnant, and i have been having random sharp shooting pain in my upper inner thigh, sometimes at the same time i get sharp pain deep in the vagina. i have also been having contractions where my tummy becomes so hard all over, and sometimes with lower abdominal pain,just like menstrual cramps.this has been going on for over 2 weeks now,however, last Sunday it got worse,occurring every 10 minutes and went on for almost an hour. then it stopped and went back to being random again.baby still moves and kicks. am i in labor?
