A warning to all ladies ttc: have often!?

After many clockwork cycles, I think I'm ovulating about 5 days early. I had ewcm today, and I'm not supposed to ovulate until Friday (according to my last 6 cycles). I still have to confirm ovulation with my bbt, but I just wanted to warn everyone that you never know when you might ovulate, so bd all the time! Luckily, my husband and I bd yesterday just because we wanted to. Otherwise I may have missed ovulation this month. And just so this doesn't get deleted, does anyone have similar stories? Have you ovulated at an unexpected time and missed your fertile window? Good luck everyone!
