Had a mc on June 13, got a positive OPK July 4. Been checkin cm for this whole cycle. Got the EWCM from OPK & a couple days after. Then today it's milky, thin to stretch & just a tad stretchy. Confused, we'll bd for the fun of it, but when to test or what. Glow is also calling today 28 cd with AF to begin 19th?? Usually 30 days so I should start around 13th..​
