But I do have Question for those mommies who are having twins... I read the post about the symptoms and I have to say o have t been able to sleep on my stomach for at least a month or have my 3 year old lay on it either (I'm 8 weeks on Wednesday) my stomach is pretty big, could just be bloat. Also I have been sick all day and can't eat much I was sick with my son, but that was more the smells of food made me nauseous, this all day sickness is the worst experience ever! Constant nausea. Where any of you able to hear 2 heartbeats before the ultra sound confirmed twins? My doctors office doesn't do an ultra sound until 18 weeks ....
