I need a buddy too. This TTC stuff is hard to go at alone. I try to talk to DH, but he just nods his head, because he doesn't understand a lick of what I'm saying! AF was the 5th for me, but I normally have a 30-31 day cycle. I'm not sure when I ovulated, as I've been a bit lazy this cycle and had a laid back attitude.
I noticed my son is only about a week older than yours! He's precious!
Good luck TTC. Hopefully you aren't here too long! I think this is our third cycle after a loss in March/April.
