Period being late on clomid?

Crystal • Pregnant with Rainbow baby
This is my second round of clomid and my first cycle on it went for 34 days. My cycle if regular every month 26-28 days. Glow has AF showing her ugly face Sunday but I don't know what to expect. I'm not sure when I o'd because I wasn't tracking it. How long has clomid pushed your cycle back? Don't want to get my hopes up and waste money on tests if she doesn't show Sunday.
