I had a D&C on December 4th. The last week or so I've been having a dull on and off pain on my left side and back. No other symptoms. We just started trying again this week. Is it possible I could have left over tissue? I have an appointment scheduled for Monday with my OB. In 2017 I had an cyst removed on my left side from endometriosis. I've had what seems to be 2 norma lull periods.
