Absolutely distraught.

I went to my first appointment today (7weeks 2days) after nervously taking another test (which was positive), and they told me my results were inconclusive. I was not expecting this at all because of all my positive results. I have been spotting but it has only been brown blood and nothing extremely serious. I’ve had a miscarriage before and have not experienced anything remotely close to what I experienced before… So instead of getting an ultrasound like I thought I was going to get, I had to get my blood drawn and now I have to wait until tomorrow for the results. I am devastated. Has anyone else experienced anything like this?
