No period?

Layla
Still no signs off a period even after 2 months. I know I'm not pregnant, that I'm certain of. Took a test and came back negative. So what other reason(s) would I be this late at having a period? I get the cramps and then they go away after about an hour, not fatigue or bloated or super hungry. It would be super helpful if y'all have any enlightenment on this. Thank you in advance
