I'm sorry your appointment went that way Have you called to reschedule elsewhere? I think the anxieties are normal...I have symptoms and my husband seems to think I am showing already (I didn't ask for his thoughts on this ) but I am still preparing myself for the worst and have those same fears. I hope you are able to get in to someone else quickly!
I have been feeling axiety too. Like raining in the excitement with "you dont know what will happen. It is still early you might still have mc even if you saw heartbeat. There might just be one in next scan" and so on.. not fun..
