I'm really late.

This is the second time (im aware of). Last year it happened in February I was on cycle day 73. Now this time I'm on 76. And as you can all see, I'm very irregular. Last year I got an ultrasound and it looked like my ovaries don't have cysts, blood work looks good. Only thing that was off was low on vitamin d. (I've been walking out more often now and taking vitamin d pills) And I was low on cortisol. Second cortisol test looked normal so they ignored it. I took preg tests in Aug 2 and Aug 18 and Aug 19 in the morning, all came back negative. I've been having some mild cramps in my lower back and hip on my right side. Only two times were a bit deep and harsh like normally where my ovaries should be. Anyone else going through something similar as this? I'm just tired and it's 1 am rn
