10dpo need some insight

Katie
So today I'm 10dpo, took a test just to check for fun, negative. I normally cramp a week in advance before my af. Which is due on Friday. No cramps, I've had one cramp yesterday and one again this morning, that's been it. I've had headaches and have felt light headed but no other symptoms..I'm hoping these little to zero cramps is a good thing cuz I ALWAYS cramp a week in advance. Even though I got a negative do you think I'm still in? Any thoughts or experiences would be great! Thanks y'all
