Clomid question

Hi ladies. This is my 2nd month on Clomid and Estradiol. AF was due today but nothing yet. I had lots of mucus today with light pink blood (sorry TMI) but nothing the rest of the day. I have light cramps but my boobs don’t hurt. They hurt tremendously around AF. Does the mix of Clomid and estradiol tend to do this? Does anyone have a similar experience?
