Hello dear,I understand your concern.In my opinion the problems which are faced in 35 + woman are miscarriages,diabetes,hypertension,intrauterine growth retardation etc.As you are only 5 weeks pregnant only ultrasound is needed at this point to confirm the correct status of pregnancy.All the other investigations can be done at respected times.BP and weight are checked ay every visit.Glucose tolerance test is done after 20 weeks for diabetes.All routine investigations are done next 1 or 2 visits.Take healthy nutritional diet and avoid physical and mental strain which are very important. Best regards...Dr srilatha
