nexplanon advice

Hi! So I just need like a bit of reassurance or just something haha, I got nexplanon a few months ago and I’ve loved it. I’ve been having unprotected sex and what not for awhile and it’s starting to get to me whether or not this implant is working.

I was on the pill for what seems like an eternity and now going to something I’m not actively taking is making me concerned.

Reassurance or advise about anxiety would be appreciated haha, I know it’s not 100% but 😬.
