No CM change since mc, cervix high and tight

Dyasha
I've been monitoring my cm for years. It's had a very predictable cycle. I know when to expect which type, etc and it's usually on time. FF to a chemical pregnancy/mc 2 cycles ago and now my CM is steadily dry/ thick. I haven't had EWCM since. Also, my cervix is always high and tight. It should be low and open but nope. It's up there and shut. Suggestions? Ideas? My dh and I are passively ttc but it's been almost a year and nothing.
