Pregnant or Pcos

I am 8 days late for my period. Which is weird as hell for me. I’m usually pretty regular. My dates will fluctuate by a couple of days up or down but I haven’t missed my period for this long since I was a little girl. I’ve been under a tremendous amount of stress over the past 2-3 weeks but I’m ALWAYS under stress due to work, finances and my relationship so why would that matter now? I took two pregnancy tests. 1st one on day 4 second one on day 6 both negative. I have been dying to have a baby with no success for years now. I’m 37 and recently was told I have DOR, vitamin d deficiency and high testosterone. I started treating the vitamin deficiency at home. But it’s only been about 2 weeks. Idk I just feel like I’m losing it over wanting this to be the one. I wish my period would just come if I’m not pregnant so I can stop guessing. That first negative test took me out. I cried more than I’ve ever cried before and have little to no support from my partner I. This matter. - this overall just sucks.
