Ovulation

I lost my premature baby over a year ago, now we're starting to try again for #2...
He works out of state a lot & tend to miss the chances. I had my period june 6, so this would be fertile week. My husband was home sunday, monday and Tuesday and we had sex..ovulation suppose to come tmr what are my chances of pregnancy? He comes home tonight and we can try tonight and tmr as well to try. Any thoughts? Thanks
