nexplanon

so i’ve been on nexplanon for almost 2 years, been spottinh for about 1 year continuously, me and my boyfriend have had unprotected sex a lot here recently and he has been finishing inside of me. i haven’t been bleeding/spottinh since november 12th. from the 12th-26th i had white discharge you could say, and then on the 26th i randomly start bleeding again. is that normal or
