Nexplanon implant and period like cramps

I’ve had the implant for 2 years and it’s great that I haven’t had a pregnancy scare. However, my periods are so irregular it’s a joke. I keep track of my periods on an app called Flo and my cycle seems really abnormal. One month I’d be spotting for a week then my period would be over, the next month I’d either miss the whole month or I’d be bleeding on and off for 12 days or more, stop and be on again a week or 2 later, it’s never the same week every month. I can’t keep up with how irregular it is so I’m thinking to change contraception.

Have chronic thrush. Trying to constantly battle doctors to get it treated but they say it’s nothing to do with the implant 😕

Positives of the Nexplexon implant is it is a very effective contraceptive and the insertion was quick and painless. However, I have been constantly bleeding (spotting and heavier bleeding) since I had it inserted 6 months ago. I have had bad cramping and lower back pain along side the bleeding. My overall mood has been effected as I feel exhausted most of the time, although I do work some night shifts so this may be a contributing factor. My sex drive has been lower than normal. I have noticed my boobs ache and feel sore. I am considering having it removed, if the bleeding does not settle.
