Was outside & was very cold for about an hour and a half. i'm in early pregnancy. could being cold for that long hurt the pregnancy or the baby? help

Most likely not: Women's bodies are amazingly set up to protect a pregnancy, even in cold weather. First of all, the baby is in the exact core of your body. Second, you probably have an extra layer of "insulation" around your abdomen, buttocks, and thighs. The reason that women are put together this way is to make sure that any viable pregnancy has the best chance at success. I think your baby will be just fine.
