Low fertile days

I know glow isn’t always right but I used the clear blue ovulation kit and it was a O. Then I used the strip tests and there were two dark lines. The line wasn’t as dark as the control line tho. I had a lot of EWCM the past four days, so maybe I missed my fertile days already? It was like right after my period tho! Maybe that’s when I ovulate? Is that possible? Gosh I feel like I should know more about my own body but it’s confusing. Hopefully my tests will keep getting stronger tho- according to glow I should ovulate in a few more days. This is month four of ttc for us, I really thought it would happen right away. I know there’s ladies out there that have been ttc for much longer so I don’t mean to offend anyone- I just thought it would be easy. The first three months I was obsessed with tracking- and it didn’t do shit haha. I’m trying to not worry about it as much but I’d like to figure out when my actual fertile day is!
