Hi, Im new to this forum, and would really appreciate some advice. Went to my doc today and she did a scan. I think I am only four or five weeks pregnant. The sac was totally visible, but no heartbeat yet. The doc says it is just beacause it is too soon, and that I should go back for another scan next week. Does this sound normal? I was so happy before but now im a bit nervous but not sure if im just being silly???? I really appreciate any advice! Thankyou!
