I have been on Sprintec 28 for 4 months now and my bleeding is all out of wack. This month I bled the first week, not the second, then bled for 13 days straight, skipped a few and now I m bleeding again. Last month was similar. All this bleeding is annoying. Is this normal? Too much? Also, because the white pills are inactive does that mean I can get pregnant the week I m taking them? Thanks.
