Body acting strangely please help.

Hi,

First of all i have PSOS, My periods usually about every 6 weeks, i am in my 30's and trying for a baby. I am now 8 weeks without a period.. I say with out, all i had this time was 5 days of *spotting* With nothing else. (Not the full blown heavy painful ones i usually experiance). 3 Negitive Home Pregnancy tests and 1 negitive blood pregnancy test. (As my dr thought i might be pregnant)

Feeling sick every day for the last week and a bit, hold/cold flushes (With no other *cold like symptons) Not only that, i feeling boated, but not contipation. I've lost weight too, but my stomach remains slightly distented.

Suffering from back pain as usual, but period usual releaves it for a few weeks and because period not usual.. is not gone away this time,

Please please please please Help. I hate being in the dark. Dr's appiontment booked for monday, but if anyone could give some knowledge on this would be great,

Shaz
