pregnant?

Tara

I had a miscarriage about nine months ago. my periods have been a little weird since then, shorter, sometimes a couple days late until this month, I am currently 16 days late. I had a blood test taken when I was 14 days late & they said it was a big fat negative. my period hasn't been late like this since I had the miscarriage... I'm loosing all hope, I don't know what to do or think. does any one have any advice or has something similar? I'm gonna be setting up a doctor's appointment soon. I've had mood swings like crazy, crazy breast changes and lots of discharge pretty much non-stop since my ovulation.
