Abdominal pain 3 weeks after surgical miscarriage

Liz • Late in my child-bearing years I have met the love of my life and we are so eager to become parents.
I'm experiencing abdominal pain in my left side and it is also tender to touch. I had surgical management of a missed miscarriage just over 3 weeks ago - minimal bleeding, which has now stopped and no other symptoms. (Apart from a slight UTI which the GAU gave me antibiotics for. I've yet to do a pregnancy test to check if any products of conception are left. I've been sexually active again since a week after the surgery. I'm concerned about this pain but before calling GAU wanted to see if any of you ladies out there have experienced anything similar. Advice please.
