Fertile cm 2x 4 days apart

Hey guys! I’m not very privy to the cm game. I do know typically when I am ovulating or getting ready to bc of the wet watery cm I get typically around cd 14. Well this cycle I had it days 13, 14, and 15. Then dry, then again on cd 18. And it was quite a bit as it felt like I peed my pants but I know it was the same fertile cm as I get while ovulating. My question is.. even though it wasn’t a few days of this cm on cd 18, does that mean I ovulated again? Only 3/4 days later? So confused…

Thanks!
