HELP!??

According to Glow my most fertile day was Tuesday.. Normally I know when I'm ovulating by signs my body gives.. On that day.. Nothing! Well today which is in my non fertile days..I'm having all of the symptoms I do when I'm ovulating.. 12 days until my next period.I think I ovulated a little late..is that normal? My husband and I had sex yesterday morning..If no sex tonight is it still a chance that I could get my BFP!!!???
