What do yu think our chances are of gettn preg, we've had sex once yesterday, and 2 times today and I am right smack in the middle of my fertile/ovulation window

I went through a MC July 4th 14. And I've had 2 full cycles since, jus ended AF Sept 8th, and I'm back on my 27 day cycle. So I am really realllllyyyy praying I get pregnant!
