I have an Ava Bracelet to help TTC tracking temp, sleep and everything else.

I was waiting patiently durning the TWW stage an now my AF is late by 3 days! January 9th i went to the bathroom and when I wiped I had alil old blood with pink blood

Now I’m noticing cramping more, I just wanna sleep, my boobs feel heavy and sore, I’m bloated like no tomorrow, going to the bathroom more, constipated, feeling dizzy and lightheaded, feeling alil nauseous more then usual... I’m now 3 days late! One app says 4 but I’m going by glow and flow since there closest to each other! Ava is about 4 days!
