My daughter is 6 months old and I have been on the rigevidon pill since my 6 week check..up until a week ago when I was changed onto the cerelle pill due to breakthrough bleeding. In the week I've been on the new pill the bleeding has gone from breakthrough/only just about needing a pad just to save little marks on underwear, to full blown very heavy period like bleeding. Am I going to have to ride it out and wait for it to pass or is that not right?
