Many women are scared of that...
Don't be...Make sure you go to the doctor when you are supposed to, take your vitamins and listen to everything he/she tells you...They do know best (most of the time)
i have read many articles on miscarriage because I am terrified of the same thing....Terrified..And most of the articles say that there's not really a way to prevent it, and they really don't know what causes it...Just keep listening to the doctor and keep your spirits up...Don't let yourself think the worst.
