I think its the bcp that messes up my cycles. I get to a regular (kind of) cycle, then once i conceive, when i've had baby i go onto bcp, but then wjen i come off it, i'm all messed up again, although this time its taking way longer than usual, and way more messed up that usual. I'm not sure if maybe age & other factors might have something to do with it. But once i hit the 6month mark i will be going to doctors for tests :-/ i do of course hope i dont have to do that, but time will tell.........
