Monalisa's Trying To Conceive Wish

I wish I could decide if I want another child soon or not. I keep thinking when I get Lex out of diapers I'll try.. but half of me just wants Lex to have a playmate as close to age as Lex. Plus there is the added who knows of TTC and the fact that I've had miscarriages. I don't know what to do!
