Positive OPK sunday night, ovulated yesterday, am i still fertile today?

me and hubby BD on sunday morning, and monday morning. we were going to last night but fell asleep! :( should we try again tonight or is it too late? i know it wouldn't hurt to try again, but what i really want to know is if i'm still fertile??? i know once you get a positive (which i did sunday night), you need to BD within the next 24-48 hours. if we happen to not be able to do it tonight will i be good with doing it the day before and day of? if i ovulated yesterday, is the egg still there today meaning i'm still fertile??? thanks ladies! :) xoxoxox
