Spasms at 4 weeks 5 days. Could it be round ligament pain?

I'm only 4 weeks 5 days getting a sharp pain off to the left towards my hip. It seems to be responsive to movement. I had this 4 weeks before a missed miscarriage in Feb. The Dr said it was pain due to having a weird shaped uterus. It went away and then I miscarried about 4 weeks later. I found out since that I have a reversed uterus. Was this pain connected to my miscarriage or just a coincidence? I'm getting the pain again. Should I prepare for the worst?
