Okay guys I’m so confused on my body like I just need help! Please...

my sex drive has went up tremendously well today I’ve had more like egg white discharge and then when I went to the bathroom at work I had like a brown stringy discharge which I usually get after my period sometimes but this time I got it before my period because my period isn’t supposed to star till Sunday. I’m having some cramps right now but not period cramps. So if anyone has been through this or knows what going on please help. Because I’ve googled it and it tells me I’m ovulating but I’ve been all my ovulating apps tell me I’m out of my fertility window.
