Discharge

Question, I’m TTC was taking clomid for 3 cycles ... finally ovulated 🙌🏾 was told by my doctor not to take any this cycle.. had my 21 day progesterone blood work today (of course want get any results until next week) my most fertile days were last week like the 5th-11th (which I had intercourse) today I had some discharge no iching , or irritation at all... I felt a little different down there 👇 and went to the restroom and when I wiped it was like a thick white discharge expected period is in 9 days any ideas what this could be?
