This is our 1st month TTC. According to Ovia app, should have O'ed on 4/27. I've had this snot-like CM since 5dpo (big glob of it then). Currently 12DPO, AF should arrive between today-Thurs. I've had AF cramps and terrible backache since 5/2. BFNs since 9DPO, but if AF doesn't show by Friday pm, I'll test again. This is also my 1st month charting CM, but I've read this kind of CM could be a sign of mucus plug forming? Anyone else get this before BFP? (sorry if photo is TMI or if I posted on wrong board!!)
