Clomid confusion

Brittany

So I’m super confused on how this works and I know everyone is different. This is my first round of Clomid, taken cd 5-9, after ttc for 13 months and not ovulating the doctor decided to see if it would work. My periods have always been like clockwork and almost to the hour my entire life since having them, 28 days. Tomorrow will be cycle day 32 and no af and a bfn test. Had an ER trip a week ago for severe vomiting that caused me to pass out after standing up, blood test was negative at the hospital but I feel I ovulated around the 4th-5th of July, which would be top end 11 dpo today. What I’m not clear on is the light brown tinged discharge I’ve been having for the past 5-6 days and slight lower abdominal discomfort I’ve been having. Has anyone else experienced this with Clomid? I know it can sometimes delay your period but I’m now 3 days late and I’m so confused.
