Worried :/

So I found out on November 7th that I was pregnant. My last period was October 3rd and my next was due November 2nd. It never came so on November 7th I took the pregnant test which came back positive. I went ahead and scheduled what would have been my 8 week ultrasound for December 1st. When I went they said I was measuring at 6wks 5days and all that could be seen was a gestational sac and that the yolk was a little larger than it should be for this time. They took blood and I go back on Friday to have more blood taken to test my hormone levels.... And they scheduled me for another ultrasound in 2 weeks on December 14th. They told me not to worry as of now I'm still "pregnant" but I couldn't help but to just cry and cry.... I'm really scared... We were so excited about our little peanut. And I know blighted Ovums are common... But has anyone else has a similar experience and had everything be okay?
