The symptoms you describe sound as though you are pregnant. Tests don't always show up whether you are pregnant. I would suggest trying another brand, going and getting a blood test from your doctor and simply waiting it out to find out whether you are pregnant!

I have had several symptoms and have done a couple of tests (one by my doctor) all of which have come back negative - but I now don't feel like I am pregnant! *mood*

perhaps you will just have to play the waiting game....Good luck and I hope you get the answer you want soon.

You need to go to the doctors and get a blood test if you don't start your period. You clearly have preg. Symptoms but hpt are coming negative so you need to go see your doctor.
