My cycle has always been the same since I first got it (5 days; first 2 days heavy, third day in the middle, and last 2 days light). Now been on birth control pills for the last 2 years which kept my period the same (4-5 days). This pill I'm on now I've been using for over a year but all of a sudden since March my period been acting up. Lately its been lasting 8-9 days and super light (like spotting light). And I just had it my period the third week of May and just got it again the first week of this month. Its now been 10 days and I still have my light period. Is there something wrong? Should I go see my obgyn? I don't understand why it changed out of nowhere. Not to mention since March I now be getting heartburn and being feeling more nausea? I need to understand this. I'm 22 years old.
