Initially I didn't notice any negative side effects other than irregular periods and spotting. However, as time went on I noticed an increase in weight which was unexplained (I was training for a half marathon and regularly going to the gym but my weight was still creeping on). I also experienced mood swings, anxiety and low mood. I also lost my sex drive completely, all of which effected my relationship. After getting the implant removed I immediately felt a lot better, and decided to give my body a break from hormonal intervention.
I felt better within a couple of weeks and I think my periods returned within a month or 2 (its been 2 years since I came off this so can't remember for certain)
Cycle return to normal
No side effects provided
