i have been on Yazflex for a round a year now, i had a 4 day break (like you normally should) 25 days ago, but my problem is that i still am bleeding after these 25 days, its not a full on period its more like spotting. It normally only occurs at night. This has only happened to me on while i have been Yaz, could it be the pill? ( i was on levlen and this didnt happen) or could it more be like chlaymdia or ghonnera? the last time i had unprottected oral sex/sex was Jan 5th 2014... i have done a urine test, just waiting for results, but im just wanting other peoples opinions because i am extremely worried.
