Feeling really down

Feeling really deflated because every single month I get spotting for days before my period. I’ve had every test going and they can’t find anything wrong but still it keeps happening. And now yesterday, just 6dpo I’ve started spotting again, the earliest yet. Next to nothing there and is brown/beige now, was dark brown when began yesterday. Today only on wiping, yesterday was in my pants. I don’t know what to do any more. I’ve tried reflexology to regulate my bleeding. My period (full flow) is every 28 days or so but this spotting for the week beforehand is doing my head in, every month I like to think it’s implantation bleeding but I’m sick of this rollercoaster of emotion with nothing positive to show for it 😞
