So scared.

I confirmed my oregnancy on the 30th of may. Today, I thought it would be fun to take a cheap pregnancy test to see the red line really darkly. There was no line to be found so I took my last digital test since I had one left over from testing on the 30th. It said not pregnant. I haven't bled any but, I'm a little crampy. We have had a miscarriage before we got pregnant with our daughter and are so scared that it is happening again. Any thoughts? I am so scared. :(
