17 DPO and BFN. anyone else?

Melissa • Due December 13 👶🏻
My period has never been four days late in my entire time having it. I know that I've only been off the pill for a couple of cycles, but my first period off the pill was same day it's always been. I'm trying so hard to accept the negative and not symptom spot - BUT I've barely eaten a thing for going on three days now (not always active nausea, sometimes just lack of appetite) with sore boobs. NONE of this is normal for me. Anybody else ever experienced anything like this and ended up with a BFP
