Anxiety

I know there are a lot of posts about us being nervous for our first appointments but I am making myself sick I'm so anxious. I am 8 weeks 3 days and my appointment is on Monday. I'm so nervous I'll go in and they won't find a heartbeat. I know there isn't anything I can do so worrying is pointless but I just want this so badly. My friend went in for her 1st appointment Friday and there was no heartbeat so that is making me nervous as well. My lack of symptoms isn't helping either. Aside from having sore breasts and fatigue there are no other symptoms. I wish there was something I could do to set my mind at ease.
