I took a test and it came out negative, I took a few and they all were negative so I started a new pack around late January but I didn't finish it so I started another one... Took my last pull Sunday or Monday... So I'm on the sugar pill week basically no period what so ever and no sign of it. And yes I'm sexually active and no I don't use protection but BC... But bc of PCOS I'm not worried about pregnancy cause I know my chances are extremely low... What can it be?
