Ttc question

So my husband is coming home for the weekend and we have been TTC for awhile now which is very difficult with him being away for work all the time. But anyway according to glow I start my fertile week on Saturday he's coming home Friday night we plan on using pressed Friday night, Saturday, and Sunday before he leaves. My most fertile day according to glow is Wednesday. If we BD on those three days using pressed is there a good chance by the time I ovulate I could get pregnant. I'm really hoping this is our month we are hoping for our rainbow baby.
