Super Frustrated

Alex • Married to my best friend and the love of my life -- my Airman. Michigan born and raised. TTC #1!
I'm not sure where to post this and I hope it's not TMI for some people, but I'm confused. My hubby and I baby danced Thursday (8/27) and I'm pretty sure I had the egg white, stretchy CM that is a good indicator of ovulation. There was quite a lot too after we finished. According to Glow, however, my fertile window should have started Friday and it goes until the 3rd of September, with the 1st being my highest chance of conception. Well, I've checked my CM again and it's a little more whitish/cloudy. So I guess I could have ovulated a little earlier than I thought? I'm so frustrated because I'm not sure when my window really is anymore. I've been trying to track everything from my CM to my body temperature. I'll definitely be looking in to buying some OPK's for my next cycle, hopefully I'll have more luck with those! I know everyone's different, but any of you ladies have tips or ways that you've been tracking your ovulation without the OPK's? AF isn't usually regular (except for these last two cycles, so we'll see what happens with the next one).
