How do you decide if you want to try for another baby and when?

the first pregnancy was early in our relationship (he's almost 4 now) and unplanned. We knew already we wanted at least one more.

We got married last January and I was pregnant with our second by the next month - he's 8 months now.

We both kinda want another but not 100%. I'd like to be done by 35 ( I'll be 33 this year). I'm in my best friends wedding next April and I don't want to be pregnant for that. We were talking about trying after that.
