TMI discharge pic

I need help! This is just a little I put on my finger I had a ton on my toilet paper but it was hard to see, I've been discharging this white/gooey stuff so much! Yesterday I thought I got my period but it was this CM coming out. I haven't gotten my period in a month and I've been feeling exhausted, super light cramps, sore boobs but yesterday I got a negitive pregnancy test!!! What is going on!? Please help!
