Question!

So I am aware that fertile window is 5 days before ovulation and you can get pregnant by having unprotected sex on any of those days. But are the chances much lower on the 4th and 5th day before than say the 3 days leading up to? I had unprotected sex 4 days before I ovulated, only once. I am really hoping I have a good chance here haha, what do y’all think? Has this been the case for any of you who ended up being pregnant?

TIA! :)
