38 Weeks With Severe Indegestion I Am 38 Weeks Pregnant And Have Severe Pelvic And Lower Back Pain, What Could Be The Cause?

I am 38 weeks pregnant and have severe pelvic and lower back pain, what could be the cause? - 38 weeks with severe indegestion

This is my first pregnancy and I had no complications so far. I had contractions, even if I did not cramp, but seriously, come and go? My pelvic pain is so bad, he can hardly walk sometimes. The pain has been for a while, but today has risen sharply. I wonder if I should go to the emergency room?
