Plz plz plz read I’m losing it

My LMP was September 16 through 20. My partner and I had sex at the beginning of my fertile window according to Glow which was sept 26 and again on the 1st(both times he came in me)which Glow says I ovulated on the 1st(not sure the app is accurate after all it’s not in my body to know🙄) but on the 27th through 29th I started gettin really bad cramps that’s lasted for about 10 mins, headaches, and hot flashes and ALOT of white thick discharge I perceived it was the ovulation process. On the 8th we had sex again not rough and I was on top when we finished I went to clean up used the bathroom and noticed some spotting it didn’t last long and the next morning I went to the bathroom and had slight pink tinge in my CM(sorry TMI) and since that day I’ve had slight cramps in my lower abdomen that comes and goes throughout the day. Slight nausea no vomit but very close my mouth gets that nasty salivating taste when you’re about to puke and gets worse if I do not eat or if I’m riding in a car for a period of time, normally I’ll eat 1 big meal a day(my appetite isn’t all that good) but lately I’ve been hungrier more, bouts of heartburn, and certain smells makes me turn my nose up, sore throat and constant sneezing( thinking it’s bc my nose is more sensitive to smells , I’m more “lazier” I’ll sleep all day despite having a good nights rest and constipation. I took a test using the first urine this morning 10/11/19 and BFN plz helppp I feel like I’m losing my mind here😒
