Pregnant from 4 days before ovulation?

erin
Any of you ladies have sex 3-4 days before ovulation day and still get pregnant? I will be home for Christmas but hubby has to stay behind and work during our fertile window 😢😢😢😢 we will be able to have sex CD 18 and CD 22-23, I usually ovulate around 21-23. Can anyone give me a glimmer of hope?! I am praying for a Christmas miracle!!
