Wtf? Ok so I'm on a 3 month cycle birth control (seasonique) and I'm not due for a period for 2 weeks. I'm having light pink spotting. I've been on it for almost 6 months and only missed one pill ever. What's going on? Im also dealing with some other issues with my lady bits.. maybe that has something to do with light spotting?
