I had a normal vaginal delivery I was bleeding till around the 3rd week then it stoped for week and half and started bleeding again at 5 weeks at first I thought it was my period but the blood flow is not getting lighter (not that it's heavy) like it would when on your period and it's now been 7 days since the bleeding started again and usually my periods are 5 days but I know it could change, but I don't see any sign of this stopping, is it normal to stop bleeding after giving birth and then start bleeding again ?
