Prenatal care??

Hi everyone, My husband and I are just now TTC he has one son from previous marriage but we have none together we've been married 15 years and this is the first time we have actually started to try before we didn't do anything to prevent it but now we are going to dr. And working on healthy diet. My question is I am 33yrs old 4'9 a little over weight but not to much. I have history of low calcium deficiency. And my bones hurt due to onset of osteoporosis. I am starting prenatal vitamins but is there anything that you ladies would recommend it do to help with being able to make sure I'm as safe as possible and the baby when and if it happens. Thanks
