Ready for the 3rd baby

My husband just got a amazing job making 5x what he was, We just bought a house got new cars. Husband and I havent been this happy content in years (since we met) things are looking amazing for us the kids this whole situation!

I didnt TRY for the first 2 babies, They just came on their own time ;)
I dont know when i ovulate or any of that i dont know where to start how to "try" i dont want to try and then it not happen lol

Advice? Do i need to see a dr?

Just do it frequently and pay special attention to the days closest to the middle of your cycle. We got pregnant after 2 cycles of trying
