Baby Fever Help

Hi ladies! I need some help because my baby fever is RAGING! My fiancé and I want to start our family basically right after the wedding (yes, we've thought it through and it's the right plan for us). My problem is Idk if I can make it the couple months to start trying. Everytime I see a baby or a child I just get all giddy and when we make love I can't be on top anymore because I don't trust myself to get off when he says he's going to cum. Did anyone else struggle with being patient? Does anyone have tips?
