go to the hospital (or preferrably a different one) and demand to be seen.
all your symptoms etc aren't 'normal pregnancy ones' as you so often hear and they need to check you over PROPERLY.
tell them your not leaving till you find out some answers for all these things.
all the things you've listed are things that they say 'phone straight away' for, so they really have to check you out.
poor thing, i hope you get some help xx
