Hi .. I Was On Clomiphene After My Periods For

Hi .. I was on clomiphene after my periods for 5 days ... Then on progynova ... I took a hcg 10000 units injection on 1st August and My ovulation was on the 2nd August ... After which I was put on duphaston for 14 days ... Today is the 16th of August n I am due for my periods ... One dose of duphaston is still remaining .. Can I expect periods while still on duphaston... Or can I consider it as a missed period ??
