CM confusing

Hi friends! This is my first month TTC and my first glow post. I have been tracking my ovulation using CM bbt and OPKs for a few months however so I'm not really new to tracking. I'm having some conflicting signs and I would

Love to know if anyone experience similar or has any answers :)

So this month my bbt and my OPT seem to agree. I used Clearblue Advanced which tells you when your estrogen increased and then when your LH surge comes on. My LH surge happened the day my BTT went down and then spiked. Makes sense.

However, I did not have any CM during that few day ovulation period. I did start to have eggwhite CM BEFORE LH surge and a lot of infertile looking CM AFTER I know ovulation ended, but none during.

Another strange symptom. My vagina walls seemed to be VERY tight during peak fertility (to the point it was hard to do the BD) :( . Me and my hubby both noticed.

Idk why this happened. My theory is that my CM was up there but not coming out of my V, just pooling up by my cervix. In a sense trapped by the vagina walls squeezed together. I could probe for the CM and got a little CM but again even with my finger I could feel how tight I was. SO WEIRD might I add.

Had anyone had a similar situation? Especially with swollen or tight vagina walls as ovulation approaches? Maybe a symptom of estrogen? It does not hurt or itch at all btw. I never heard of it happening
