Confused

Sabrina • Mommy of 2 C-section baby boys. Bryson Stan, born July 26th 2016 and Jackson Xavier born June 4th 2018.

I’m on the nexplanon birth control my last period was April 8th-14th, yesterday the 28th I guess I spotted, I’ve changed my pad and there was hardly anything and nothing in the new pad. My periods have been pretty unpredictable since having nexplanon implant put it last August. And between my periods I’d spot for a few days to a week. And it’s been a few weeks since the last time me and my S/O had sex since he’s away trying to get us started up in another town and working. I know pregnancy is highly unlikely but can be possible, but be an ectopic pregnancy if anything. Should I be worried... idk what to do...
