so i am 16 and i started on nuvaring about 6 months ago, maybe more. this past month i have been bleeding a large amount while the ring was still in. i never take mine out to get my period. i just change it. however this time (2 days ago) i took it out. my bleeding has started to decrease since i took it out. i have had sharp stomach pain with diraeha and migraines. i’m worries about preganancy. help?!
