Ovulation Help

So I’m not doing OPKs yet. Just basing my ovulation off what the app is saying. Hubby and I have BD every other day all month. Today I’m supposedly ovulating. Hubby and I BD but wasn’t able to inseminate. He was mad he couldn’t and said he wanted to try again tonight. Does it hurt to try later today? I guess I’m just not sure what’s best. Considering we aren’t doing OPKs yet and truly don’t know if I’m really ovulating. This is the first time in 2 weeks he’s not been able to so I feel like not stressing about today is okay. HALP.

Also I know that we don’t have to BD everyday it’s just a preference.
