Ovulation Help!

My husband is in the military so he’s gone for the next couple weeks. Before he left, Sunday, we had intercourse. I just took an ovulation test (clearblue digital) and it says “high fertility”. Sadly since he won’t be home for the next two weeks, we can’t try again while I’m ovulating. Any guesses on if anyone thinks the sperm from Sunday will last the 3-5 days and I’ll get pregnant!? I’m hoping I do! (Today is day 2 since having sex).
