Nexplanon

So I’ve had nexplanon for 2 years and 10 months and today I went to try and get it taken and have new one put in because the last few months I’ve been having horrible cramps and periods and since having it I haven’t had a period, but today I went to the doctor and told them my problems and they told me to take ibuprofen but like I already have been taking ibuprofen and she told me is that if that doesn’t work that “she doesn’t know what to tell me “ her exact words and idk how to feel about it and I need opinions please.
