Does Clomid Days matter?

Katelyn

So I have taken Clomid the last 3 cycles on days 3-7. This time (4th), I started spotting and my doctor told me to not include that as a cycle day to wait for a full blown period, which was the next day.

AF usually shows up on CD28! Would taking it a day later since I was only “spotting” push my period back? I’m on CD28 or CD29 if you include the spotting day. I’m trying to figure out if I’m late. Would that have an effect on making my cycle longer or should it still be a 28DC?
