I've been on the nexplanon implement for almost 3 years and the past years I've only gotten my period 2-3 each year. The last time i got my period was april 2015. I've been having morning sicknesses and headaches mild dizziness. At first i thought it was normal that i haven't gotten my period because my provider told me that i was going get my period every 3-6months but I've been having all these pregnancy sicknesses and headaches mild dizziness for the past 3 days ... Should i worry or just get checked up
