Is there still a chance?

Was due to ovulate on Saturday (2/23) but didn’t get a positive opk until this afternoon. Problem is, hubby went out of town for work yesterday (2/24) for the next three weeks. We BD’d PM on 2/22 and 2/23 but I’m worried it won’t work for us since it was 3-4 days before I am going to ovulate. :(

I’m 34, he’s 38. Been TTC since October 2018.

If anyone was lucky and got pregnant by BDing 3-4 days before confirmed ovulation, please share here. Give me a sliver of hope. LOL.
