help?

I am currently cycle day 17 .... two days out of my glow expected "fertile window." I am a bit confused because I had some cm this morning that reminded me of how ewcm should be. It was white with some clear mixed in but did not stretch too well before breaking. I have never had ewcm, so I am not sure if my window was off. It almost seemed mucusy (sorry tmi). I checked my cervix and it it pretty high, firm, and maybe slightly open maybe closed but def not as soft andopen as it was last week. I also checked the cm that I was getting after checking my cervix and it was white and like lotion. I am probably going to bd tonight just to be safe, but what does this sound like to you guys! Like I said, last week cervix was high, soft, and open and cm was clear and watery. I am so confused 😂 thanks in advance!
