well i am in the UK and i am currently waiting for my beta results to tell me if i am pg or not .... i am lucky though as my doc puts them through for me if i request them ...and this is my GP !
He told me that they arnt supposed to do blood tests for pregnancy anymore unless an eptopic is suspected and that is what he usualy writes on the form to go with the blood to be sent off ...however this time i saw the other doctor in the surgery and i told him that my doctor normally puts them through for me as HPT's arnt that relyable with pcos ( ok so i fibbed a little) and he believed me and promptly took some blood but he wrote pcos pg query on the script ....so i guess what im trying to tell you is that all docs are different .
If you go to your doctor and explain that having pcos you have an increased risk of M/c and you would like to have your hcg levels tested to make sure everything is ok and progressing like it should be ...and also ask for a prog test too and explain that you would like this done so that you know wether you will need prog support ...tell him that you have waited and tried long enough for a baby that now you are pg that you want to do everything possible to help keep it .... im sure if you explain all of this he will draw some blood for testing

...ohh and try catching him either first thing in the morning or last thing at night <<<< strang i know but these are the best times of the day to catch a doc at his most considerate of moments
hope i have helped you out a little
love an kisses jo x x x x x x x x x
Ps please let us know your result if you manage to convince them to let you have it done !
