9 DPO

Hey, I'm 9 DPO according to Glow. Looking for implantation bleeding this morning and nothing. Only thing I'm really having is sore boobs and gas. My nipples aren't sore, just my boobs. I have bumps on my areola but none out of the norm. AF is due on the 31st. Idk what to think because I haven't had any cramps that'll make me go nuts.
