Alright people- sound off on what you wish they would have told you about pregnancy!!

My SO and I decided to toss the birth control and try for our first 😭 although I always hear you can never be fully prepared- I am curious what you would go back and say to yourself either while trying to conceive, while pregnant, about the birth, or the first year! For example some questions I have for conceiving is, how important is it to track ovulation meticulously, is it better to let it happen spontaneously? What’s the most important thing to do during pregnancy that looking back you would have done? For birth I’m thinking of a birth center and trying natural, does anyone have experiences to share about this? And my hubby is already so excited and already the best pet dad ever so I’m not worried, but is there anything I should warn him about?? Excited to hear some advice from some veterans!! (I’m only 25 and never even changed a diaper so I’m understandably nervous!)
