I had somewhat of a hard birth with my first, lost a lot of blood and bp stayed high for a long while. (had vaginal birth) she was 7lbs 7oz, I'm scared to death that with my son he will be much bigger and may have the same complications or worse... I know I should always hope for the best, but I am scared. Almost 24 weeks, I think I'm just freaking myself out lol
