BFN two days brown period and confused

So af was suppose to come on the 6th of this month. And on the 5th I got my regular thigh cramping which normally starts like 8dpo and of course the reg breast tenderness. So I can’t bet on oh it’s going to be a bfp this month. Because I started tracking all my symptoms in my tww and saw they resemble early pregnancy. Ok so again on the 5th I get the cramping in my left ovary and I’m feeling wet so I’m like well I guess I’m out af coming. Nope I wipe and see a bright pink spot on the tissue. I put a pad on just in case, and nothing the rest of the day or over night. I wake up on the 6th abs nothing all day and all night. Wake up on the 7th and now this app like your late late, and here goes another pad and nothing all day or all night. The 8th comes I get the strongest cramping in my left ovaries but I don’t take anything for it. Maybe that afternoon I feel wet I check and just brown flow. Not heavy flow not medium flow. But it was flowing enough that it left two long brown streaks all day on the pad. So I took a dollar store test that’s all I had left. It said no, so I was like okay I’m out. However I never ever ever get brown. It’s comes right on red every month, every 21-23 days I’m bleeding. And I flow so much that I mess up under clothes no matter how long the pad. So I always sleep with a period cup. Well that night nothing all night. But the 8th is here and the same thing. All day at work, just two long brown streaks no smell on the pad. I wiped and I had one small string blood clot that was burgundy and when I touch it of course it was red on my finger. After that nothing else red and it was gone that night. I normally bleed three days and have to change my pad a few times a day. Oh yeah I bbt daily and I had a dip at 6 dpp and 12dpp. Nope bbt went back down to 97.80 on day 8. And has been in the then back up to 97.98 then 98.00. I’m nervous to test since we had a chemical in April. The dollar store test said no, I used a lh test as well that was high. I don’t have by other symptoms except slight cramps in my left ovary sometimes. I’m so emotional and moody daily. My breast feel a lil tender but not much. I don’t have any discharge. My head hurts. It may be stress since I’m about to send my daughter off to college next month. Oh and this app says I’m going to ovulate in 7 days since it’s counting those two days as a period. Has this happened to anyone else?
