Talk to Gynecologist on Gynaecologist

I had an IUI cycle this month with IU 75 injections. My period was heavy and lasted longer than usual. Now, I am on cycle day 17 and still experiencing brown discharge and occasional spotting. I also had ovulation confirmed through a test. The spotting sometimes turns darker but remains light. Could this be a hormonal imbalance, infection, or a side effect of the IUI medications? Should I be concerned?"
