Pain during inter course while on the nexplanon

baddietee✨👑
I've been on the nexplanon for a bout a year and a half . I started getting the worst stomach pains during sex that would last about 15-20 mins about 5-6 months ago. Ive also been getting yeast infections and BV like crazy and Ive even passed out once . Has anyone else had this problem ? And if so what did you do about it ?
