i was on the neuva ring for 6 months and kept getting chronic UTI's. by the 6th month i just stopped my birth control completely and the UTI's stopped. once i got off my period, it came late. but im not pregnant. and now for the past 5 months i haven't had a period. i have been spotting constantly since my last period in early January. a light flow. sometimes a dark brown, pink, or blood red. it also changes textures. whats wrong with me? could i be pregant? is my body confused without the birth control? help!
