Thanks for the query.
Some of the symptoms you are describing could be side effects of the implant and some are seasonal.
After changing the contraceptive
method it will take some time to get accustomed to that particular method.
So you wait for some days, possibly the symptoms will subside soon.
Meanwhile you can take symptomatic treatment.
