"i&#039;ve been on nexplanon for 2 months now, and was well aware of all of the adverse side effects, but like others, felt as though i was not going to be the victim of these terrible reactions. i was right for the most part. i haven&#039;t had any problem with acne, weight gain (i&#039;ve lost weight, actually) or hair loss, but the bleeding, oh dear god, the bleeding... i had mine implanted during my cycle and pretty much stopped that day. i had a week menstruation-free, and have had heavy spotting to moderate bleeding everyday since. my gyno put me on norethindrone 5 mg tablets once daily to stop the bleeding a week ago. after taking them for 5 days, the spotting stopped. i was overjoyed- until i started bleeding after sex last night!
