Is it possible to get a healthy pregnancy at the age of 38?

Hello doctor,

I am 38 years old and married. I would like to have a baby within the next two years. I have been married for a couple of years but have not had proper sexual intercourse due to personal reasons (no medical reasons). Now we are almost ready, but before that, I would like to have thorough details about the pre-supplements I need to take, the required tests I need to undergo and the diet I should follow. I am 38 years old and a bit nervous about my health condition for a healthy pregnancy.

Here is some information about my lifestyle:

1. My height is 164 cm, and I weigh 130 pounds.
2. Menstrual Period Cycle: I have never missed a period. My periods occur between 27-29 days, except for a couple of times when they were 30-34 days, usually during the of high stress. The flow is typically three days full, followed by lighter days. I have never taken the test for PCOD.
3. Other Health Conditions: I have never had any serious health problems.
4. Exercise: I walk or engage in fitness activities for 1 hour a day.
5. Eating Habits: I am a vegetarian, non-smoker, and occasionally drink alcohol.

I request you provide proper guidance and the steps needed to take for a healthy pregnancy.

Thank you.
