I've been on the nexplanon implant for 2 years now. Up until February I would have two cycles a month. Well when February came I didn't have a period at all but started bleeding March 1and went off on the third. A week later I spotted light pink for a day then nothing the next day then spotted light pink again the day after that. I haven't had anymore bleeding since. Then the other day I felt a weird sensation in my stomach like little bubbles or something idk I can't describe it. Someone please help
