hey guys so i’m a bit concerned rn. i am on nexplanon and have been for the past 4 years. I got a new one reinserted over a year ago. i recently became sexually active and i was using a condom. one night me and my bf didn’t use a condom and he finished inside. i was super paranoid so i took a plan b and my period started a few days later. but i’ve been bleeding for the past 16 days and it’s gotten heavier idk if this is a side effect of taking plan b or nexplanon or if i should get checked out.
