This is the darkest I’ve had (first month using OPKs). Cd18 and Glow estimates O will happen in 4 days (but I have irregular cycles so not reliable). Anyone think I might get my positive tomorrow? Still BDing anyway cause don’t want to miss it! This is 10:15am urine after 3 hour hold. Have mainly watery cm which seems to have increased today and a very very small amount of ewcm.
