pregnant on Nexplanon?

Chloe

my boyfriend and i have recently been having a lot of unprotected sex and with that he’s been cumming inside of me. i am on nexplanon and my period should start next week, but i’ve been having some light spotting and i’m wondering if any of you on Nexplanon spot about a week before your period and other PMS symptoms you have while on nexplanon.

i’m worries it might be implantation bleeding ?
