What CM is most fertile?

Ladies!

I’ve been ttc for 6 months to no avail. I’ve been using ovulation strips and I get one blaring positive a month but I’m not pregnant yet.

This month I decided to stop and just go by CM.

So on the 20-22nd I had super stretchy egg white CM. It would stretch several inches so I know that’s what it was. Since then I’ve had straight clear watery CM.

Which is best?!

I did the deed with egg white CM so just trying to figure out what’s going on!
