Hi guys! I literally just downloaded this app about 30 mins ago and I am trying to figure out how to navigate this whole thing. 
Here's the short story: I am 23, have very consistent periods, not in great shape but not terrible either.. and my new husband and I are TTC for the first time starting on my next fertil window.. which is early January. 
I bought some prenatal vitamins today. Other than that, any advice or tips? I am feeling very overwhelmed with all the info that is out there and had no idea there was so much to it.
