Clomid without prescription!

I ordered clomid online after trying to conceive for 3 years and finding out I have pcos and have not been ovulating. I am currently taking medroxyprogesterone (provera) to induce my periods and I took clomid on days 3-7. I didn't have any horrible symptoms other than for a few days I had a severe migraine, and a few hot spells but its summer so I can't assume it was from the clomid. I am currently on CD 13... does anyone have a positive experience from this? any tips? etc. Thanks in advance!
