Cramping..

Okay for some reason Glow doesn't have when I'm supposed to start AF but I am cycle day 35. My last 2 cycles were 44 days and 33 days so it's kinda hit or miss. Anyway my boobs are super sore not to touch but any pressure at all and I get shooting pains. I've been super tired this month but trying not to read too far into as I've had light light cramping on and off for the last 2 weeks.. has anyone else had light light cramps that long and gotten a BFP? Glow said my fertile window was October 30th- November 6th. Any advice is welcome! Ty in advance! 😁👐🏼👐🏼
