So, I recently found out im pregnant (yay). According to Planned Parenthood im 7 weeks along, im not sure if that's correct, wont know till I get my first sonogram. Anyways, im VERY petite..im 20 years old, only 5'0 & 85 pounds (no i dont have an eating disroder, always been super small) anyways, because of my petiteness. . .im highly afraid that I have a HUGE risk for miscarriage. Is there anything I can do to prevent one?
