Nexplanon

Kay
Hi guys! Tuesday I get my Nexplanon implant. I'm excited to be on of the most accurate forms of bc but also nervous because if my period will stop after a while how will I know if I'm pregnant? Also, how long does the bleeding last while my body is getting used to the hormones? I've been on the pill since I was 13, I'm now 20 but just recently lost my virginity. I'd love to here y'alls expirences with Nexplanon or even with implants in general. Thanks!
