TTC frustrations!!!

I took numerous OPKs to figure out when I would ovulate and today I get a positive and guess what!?!? My husband has to work late. I literally feel the cramps and I know my body is releasing an egg. I feel it in my ovary. If he comes home tonight and we BD do I still have a good chance? I know it’s probably a dumb question but I don’t want to miss it.
