"i got my nexplanon implant on feb. 28th. began a cycle about a week later. this cycle was different than my typical cycle, for i no longer had cramping or migraines. however, the cycle lasted for 9 days. after a few days of no bleeding, another cycle started. the second cycle lasted 5 days. then i had an additional few days off, only to start a third cycle. 
when does this end?
when does it regulate itself?
this cannot be healthy to bleed for approximately 3 weeks every month. this is the complete inverse of what it should be.
while i appreciate no cramps or migraines, i do not appreciate spending so much money on tampons and underwear....
getting frustrated, and contemplating removal."
