I had an ultrasound at 6 weeks because I had some spotting and was worried, ended up being normal. Went to my prenatal appt and doctor said I won't get another ultrasound till 18 weeks, is that normal?. Was expecting to get one at 12 weeks and I asked her twice but she said I could wait till 18 weeks. Her saying that makes me really anxious and don't want stress the baby. It would make me feel a lot better if she listened to me and had one to ease my mind.
