Best things to do for your health when TTC?

AnnaMarie • I`m AnnaMarie. Married 10/14/2017, and our son was born 7/20/2018. 💙

I've heard drink plenty of water, eat healthy, exercise everyday, etc. But are there any other things I should do? We're not trying YET, but we are going to start trying in January, so I want to get my healthy habits down now!
