Heavy creamy discharge at 7dpo??

Hi ladies, anyone have experienced heavy cream discharge at 7 dpo?

I had really bad cramps yesterday at 6 dpo and it went away today.

This morning my temp spiked up to 0.2 degrees, and i started having a gush of creamy white discharge every few hours. When it gets dry on my undies it has a very white crusty colour and it filled up almost half on the bottom crotch area of the undies.

Also yesterday and today, I get a random struck of nausea + headache in the afternoon for about 1-2 hours. Then it goes away..

Anyone experienced this before?? What is it? I know that it’s too early to experience pregnancy symptoms so i’m wondering what it is..dont usually have this in my cycle.
