I Had Cryosurgery Of My Cervix, And Didn't Bleed Until

I had cryosurgery of my cervix, and didn't bleed until about two weeks after. Then another week or two later, I had a normal period in addition to the bleeding from the surgery. The bleeding has since then stopped, but I'm due for my next period. I had bleeding the other day accompanied by the usual cramping and headache. I thought it was my period, but the bleeding only lasted one day. Should I see my obgyn?
