So I am not sure what's going on...but I think I already ovulated and missed most of my fertile window :/

A few days ago my cervix was high and I had a decent amount of CM. We did the BD a couple of those days. I don't believe I get EWCM as I've never noticed it. But today cervix is low and CM is pretty light, if any. Its like very light creamy/lotiony with a hint of stretchy, snotty opaque CM.

Should I consider this month a loss or wait to see if things get more wet again?

I started using OPKs but the dang brand I got is trash and they either don't give me a reading at all or get oversaturated every time I use it so I dont trust what it says lol. Thanks!
