Aww Emmieee, i feel for you hun.
Im 26 and i had a miscarriage back in may 2009 i was having tests done around the same time and thats when i was diagnosed with Underactive Thyroid, doc told me my body just wouldnt have been able to cope with the pregnancy and thats why i probably miscarried was about 7 weeks :( .
But i was lucky and after starting on thyroxine fell pregnant 3 months later, i have a DS age 2.
Since having DS iv been to pot and having irregular bleeding and just not 'feeling right'. Its only with going back and forwards to gp that they finally listend to me and done tests and scan ect. Thats when they suspected PCOS, but like you waiting to get it confirmed.
Its strange you say about all the symptoms your having which is soo like pregnancy symptoms, everytime i say to my friends and mum they say ohhhh your pregnant...............if only!!
The other thing is if we were to fall pregnant we probably wouldnt know for the missing periods!!!!
I do hope you get your referral through soon, and manage to get sorted, you will have to keep me posted, and i will let you know what they say when i go next month x
