People keep telling me to try for a 3rd kid

Because they see I have 2 boys. So they automatically go into the "oh try for a 3rd and get a girl. U have grandparents' help" blah blah blah. Complete strangers telling me this. First of all, grandparents won't be here forever. Second of all, they aren't here 24/7. God, I want a girl sooo bad, but also what I want sooo bad is just having 2 kids. If I had a 3rd, I'd totally feel like it would just be another boy anyways. 🙄🙄 So not only am I hearing from my parents that I should have a 3rd, I'm hearing it from strangers. Now I feel like I'm second guessing myself in my decision to only have 2. But I don't wanna have a 3rd just because I'm being pressured to. But is having a 3rd that bad? I'm honestly just scared to death. Everything will be harder with a 3rd kid.. especially a 3rd boy. Omg I'm palpitating just thinking about it. Will need a bigger car, bigger house, harder to travel with 3 kids, more expensive, etc. Sooo nervous about it.
