any moms seem to not be able to sleep til seven am, well it could be because of overnights.. but regardless if I work or not, I end up sleeping like a rock til around 2:00 pm wasting my day away after having a horrible time all night. then I wake up and feel like im going to pass out for not eating in so long, but even with alarms without fail I cannot wake up I'm so worried... I'm barely showing and haven't even felt my little one move yet and my midwife says everything's fine, a healthy little swimmer with a strong heart beat but everything I deal with, healthwise.. im worried if this is normal
