BD during flashing smiley?! Pregnant 3+ days before ovulation?!

Hi! I’ve read so many posts on here but for some reason feel like I have to post myself!!

I got a flashing smiley opk on Sunday morning, we BD in the afternoon. My husband works out of town and left for the week. I got my solid smiley opk this morning, Wednesday.

Is there a chance I’m still in it for this month?! We won’t be able to BD again until Friday afternoon when he gets home. Will that be too late? Will they last from Sunday to meet my egg?! Has anyone gotten pregnant from BD 3+ days before ovulation?!
