Help please.....

I had sex everyday for 4 days before my fertile window started. Glow says my fertile window is the 27th through the 5th. I also had sex on the 28th, the 1st, and today. According to the glow app, I should have sex tomorrow because that is my most fertile day. Does that mean, my egg will release on that day? I am completely confused, and it is stressing me out. Any advice will be appreciated.. Have been TTC for over a year.
