Pp bleeding

Ill be 7weeks postpartum tomorrow Thursday. I had stopped bleeding for a few days and it came back red almost like pd flow (not as heavy as it used to be, but enough to wear a regular pad) again it faded off and now its back. I went to see an OB at 6 weeks and everything looked good and was given the OK to be sexually active again. Could this be normal? I have another appt with a diff OB on Monday but if im bleeding doubt theyd do anything :/

Anyone else had this type of thing happen PP??? Help
