Don't know what to think!

I went to the Dr. Today for pain in my right side she decided to do a early scan vaginally and didn't see anything:( she said she isn't to worried about it right now that I may be only a few weeks pregnant. I really wish she didn't do the scan today it's got me so upset. I really want this baby to stick I just had a miscarriage last year don't think I can go through that again.!
