Fertile CM ?? 🤔

Le

So long story short, I was on Provera to regulate my periods, it has now been 2 months since I came off them.. Ive had 36 day cycles ever since, I am currently on CD 21 and I am not tracking BBT or using OPKs since it has been disappointments after trying clomid with no luck, anywho, I just noticed this CM.. it's not clear egg white, but similar.. is it fertile? we had sex yesterday morning so I figured it must be semen? not necessarily trying but hadn't had this type of CM in months!! Who knows.. 🤷🏼‍♀️
