Discharge before AF due - sign of pregnancy?

Hi ladies,
This is my 7th month TTC. My periods aren't regular (anywhere between 28 and 36 days s). I'm on day 28 of my cycle and have noticed a pale yellowish discharge today, which is creamy. Since ovulation my breath have felt heavier but not really sore. Additionally, I felt some slight cramping around 8DPO.
Any insights?
Thank you
