nexplanon

Hey an Good morning! I have the nexplanon an I got it June 13 my period was already two days late then! I finally got a period on like June 22! An it was like old blood an then it became new blood after a few days my periods usually only last 6-7 days an I am still bleeding! My hormones are everywhere! Like I'm over this! How soon will my body adjust? Or if I get it taking out how long does it take for my body to readjust? Thinking bout going on the pill
