Wondering what I should expect to see? I am so so so so so nervous. My hcg levels are nice and high but I have had a bit of spotting which my re said is totally normal and he said we may be able to see the heartbeat on Monday. I am just sure if we can't I will have a cow ? can anyone offer insight or talk me off the ledge?!
