Miscarriage fears

Courtney

This is my first child and like normal, im scared shittless. I am 5ft and weight about 180....my bmi is high. I was reading that if it is above a 30 then you have a high chance of a miscarriage. What can I do to lose weight and keep the baby safe. I am only about 5 weeks along and dont have my first appointment till the 19th and would like help now. I would do anything to keep this baby.
