Blue Pill Clomid buying online

Hi has anyone used online sites to purchase Clomid from? I tried Viagra and other medications through doctors but they dont really work and I read up that Clomid is a good alternative but the doctors I saw didnt want to prescribe. I tried ordering a batch online but the site was compromised as my credit card provider declined it and sent me a txt saying the transaction was declined by their fraud detection area and not to use the site. There are a few websites online but now a little concerned purchasing online.
