Pregnancy tips HELP!!!

What are the Do's and Dont's of pregnancy?

I want to learn everything I can before becoming pregnant.

I feel like ttc is becoming overwhelming and I'm starting to forget everything I read about what to do before your pregnant, what to do during and what to do after.

There is so much to learn and I want to be the best mother I can.

(I do understand everyone has different opinions but I just want to hear them all)
