Hi I m 24 with one child. No health issues and recentally removed the implanon after 2 and a halfway years. To replace my birth control , I am now using the nuva ring for about 2 weeks.. lately I have been feeling very nauseous through out the day and night and I now have night sweats . I have taken a pregnancy test just to make sure I wasn t pregnant and test is came back negatve. Not to mention I haven t had a period since September 29 this is not normal for me. Please help.
