I have had my nexplanon in my arm now for birth control for 2 months, and have been sexually active that entire time. Recently, however, I had my first session of spotting while on nexplanon (my Dr said this would happen) and my boyfriend usually cums in me during sex, and recently i have had sharp pain and a weird smell come from my vagina. I have had white discharge and I want to know whats wrong with me. Also, my right ovary (It seems like where my ovary is, might be mistaken for my appendix) Is slightly larger than the other side.
