Your child will anyway be at risk of having cholesterol problem since it runs in your family. You have to get your cholesterol levels controlled first and then plan pregnancy to avoid complications during pregnancy and childbirth. Controll it wil medications and also maintain a diet for yourself.
The issue is I'm 121 lbs, 5 ft 2 inches tall, excercise 1/2 hr every day and have an essentially low fat low cholesterol diet.
