Help!

I did my first round of Clomid and am ready to start my second round any day. I had a positive OPK on cd 19 and started spotting on Monday cd30, but now it's Saturday Cd35 and no AF still just light spotting. I emailed my ER to ask if spotting is cd1 or full flow is and they said if I normally have full flow then that is cd1. I usually have full flow, but have just been spotting. I'm not sure what to do! Is this af just going to be spotting should I have started clomid yesterday? Or should I keep waiting to see if the real thing comes?
