Ovulating NOW while DH is at work

So my DH and I have not been using protection for over 2 years. We figured if it happens, it happens and we are ready for it. Well, it never happened. He works second shift and I work first. So we literally ONLY see each other on the weekends. So typically we only have sex once a week. Well we recently decided that we are BEYOND ready. This is our very first month TTC. Luckily I've been monitoring my period years so I know when I ovulate. We've been trying our hardest to have as much sex as possible and we have been succeeding a lot more than normal! In the past week, we've had sex 8 times. Only problem is, I'm ovulating TODAY. Right now. He is currently at work. And I have NO way to reach him since he works at a prison. We did have sex late last night (around 11). And we will hopefully have sex tonight when he gets off work (he's just always so exhausted)... basically I just want to know if there is still a good chance of me getting pregnant from last night? I know it's not convenient that he had opposite hours, but we're trying. And we can only do so much. Any help and advice and tips are all welcome! Im new TTC so I could use ALL of the advice!
