Is my CM a good sign of ovulation?

Sooo on October 9th my Hubby and I had sex ( trying for baby #2) the next day I started my period from October 10-15th. Then we had sex again on the 15th and 18th( finished in both days ) I’ve been testing and I have nothing but negative pregnancy test. I’ve been having this type of thick clear/ foggy discharge as wells.

discharge for a few days wanted to know if this is a good sign and I should keep testing or should I just give up ?
