How many DPO should you take a pregnancy test on a Clomid cycle?

Dawn
I'm on my second cycle of Clomid, and I'm just wondering how many DPO I should wait before taking a pregnancy test. I don't know if it is any different on Clomid or the same as it would be for women who ovulate on their own. I ovulated on day 18 in my cycle and my last cycle was 34 days long.
