should we try for a 3rd?

We only wanted 2 children and wanted one of each, now im having my second boy and i really want a girl, iv always thought it would be so perfect to have each gender and i even saved so much stuff from my childhood i wanted to give a little girl.. idk what to do we really want our girl but idk how 3kids would be to handle and keep up with and financially itll be hard at 1st.. but parts of me say it would be worth it in the end.. but it could be another boy or twins 3rd time around and not sure how we would feel about that.. but we feel like we’re missing out on a girl.. what should we do? We want them close in age so it would be 3 under 3 too.. or very close to it..
