Excuse me...what?

Yeah hi its been 7 weeks since my last period and I'd just like to say WHAT THE FUCK NEXPLANON?!?!?!

I mean its been fucking with my cycle but I've been logging each period and the algorithm or whatever has been pretty good a predicting my next period with only a few days difference. Its never been THIS off. So now I'm worried bc I don't have a way to get a test right now and I'm not in much of a position to be pregnant right now either. Anybody else had Nexplanon fuck with their cycle this much out of nowhere?
