blocked fallopian tubes and cm

this maybe a stupid question but really cant find the answer to my question on the internet.

long story short, both tubes were blocked, after hsg, one side opened up. but the side that opened up is full of cysts. so it's been 6 months since hsg so decided to move onto IVF. (been ttc 9 years) but thanks to covid, my apt got cancelled. so yesterday I had fertile cm. which I never get. is it possible to have fertile cm but have blocked tube/s? could this mean I'm ovulating from my open tube??
