I am about to have my IUD removed and am seriously thinking about not using any other form of birth control. I turned 45 in August and do not have any children. It's not that I'm trying, but if it happens I will be happy. My husband have been married for 2 years and he has two daughters ages 24 and 18 from his first marriage. My sister is a Registered Nurse and thinks that it will be okay if I did become pregnant. Please give me some advice.
