Try to relax a little. It may not happen the first or second month, it could take time. Know that you have Pcos, you may want to talk to you doctor and see if you doctor can give you any advice on ttc, with pcos, they may be able to suggest how long to try on your own before suggesting further testing, etc...
It can take the average couple 6 months to a year. Most people are told seek a doctors advice after trying for 1 year.
Have you had your period since you started trying? Since it's only been about one month, you may not have caught your ovulation last cycle, and it might be too soon for you to have ovulated again this cycle, or too soon to test positive. I would suggest charting your cycle for a bit, to ensure that you know when you are ovulating to be able to hit the best days to try to get pregnant. Testing every day won't do you any good if you aren't bd'ing (baby-dancing aka making love) when you are most fertile.
Good Luck, and try not to obsess too much, that can actually hinder your chances of conceiving.
