Late Period, Pregnancy Symptoms, Faint Positive...

Just wondering what you all think..

So i havent had my period since December 2011, and its now February 2012.

I've done like 6 HPT's all negative except one had a very faint positive, went to the doctors and did a blood test and she said it as negative and i had less than 2ml HCG... 

Ive been really bloated the last 3 weeks, mild cramping, really tired, eating heaps, like pretty much every hour, really bad gas :/ 

What do you all think?

Thank you :)
