Nausea and Diarrhea just before ovulation?

Sarah
Hey everyone,
I am due to ovulate any day now (my guess based on symptoms would be Friday).
I chart my temp, look for EWCM (which is starting today in abundance) and I use opks. 
I noticed this last month and it's happening again today; just a couple days before ovulation I am super nauseated and have diarrhea (sorry for that visual). Is it just the surge in hormones or is my body rejecting itself lol. 
Anyone else experience this?
