Is there anything else ive missed?

me and my fiance have decided to start our family so today we both went to see our local doctor and he recommended some folate to get he said 0.4mg but i could only get 0.5mg and apparently thats ok dosage. he also took my blood pressure and sent me off to get a blood test to check my tyroid and all other shots that ive had recently like chicken pox and rubella plus i got the flu shot today. just wondering if he has missed anything. i also no i have to start exercising and eating a good diet and i do not drink or smoke. he said since im young it will happen easily and i dont have a lot of stress in my life so thats perfect and i no that u dont go in to make a baby we are just hoping that it happens and getting my body ready for when it does. if anyone has any tips on what ive missed out please share :) (but please dont tell me not to try and make a baby as ive already said im not focusing on it i no it happens in its own time)
