5 days until AF arrival. App is always correct as far as af dates. Spotting started yesterday - 1 wipe of bright red blood spot, small amounts of older “brown blood” since when wiping. Feeling tired and crampy, but not my usual PMS cranky bitchiness?

(TTC for 2 years, recently diagnosed with hypothyroid and this month I stopped tracking my period but I ovulated around the 20th, bd on 17th and 22nd. We weren’t “trying” this month because I’m focusing on my health - went paleo diet and started taking thyroid meds)
