Let down

I’m 37, TTC number 2 for six months, but have been having issues. I had a baby in 2017 with no issue, got pregnant in December 2019 but had a miscarriage and d&c, and now I seem unable to get pregnant again. I think I have adenomyosis and/or ashermans syndrome. Anyway, my period is 3 days late, which is incredibly odd for me, so I took a test and it’s definitely negative. I usually have a 30 day cycle like clockwork. I’m under a lot of stress at work so that’s probably the issue, but such a tease. I’m so disappointed and starting to lose hope.
