Help I've got baby fever!

My hubby and I have been married three years this August. I'm not on any bc and were aren't preventing pregnancy. We have a two year old son, and currently live with my parents. We are trying to find a house but hubby has horrible financial self control. I want another now so our children will be close in age but not too close. I'm currently on CD22 and my O day was CD17. We did the BD on CD 6, 9, 10, 11, 15, 16, 19, and 20. (A lot I know) AF is due on July 23rd and on CD19 and again yesterday and today I've had spotting. The first day was super light/faint pink an yesterday and today it's brown. I'm only 5DPO and I know it's super early but I tested the other day and it was negative. I've felt nauseous all day for the last two days, I'm going to pee every five minutes it seems, and my boobs are killing me! I'm crying at the silliest things. I don't know what to do, I'm a POAS addict and the suspense is killing me. I hate doing the TWW but I know that's what I gotta do right now.
