Still no period…

My period is 107 days late, my last cycle was 10-02-2021 and pregnancy tests came back negative. Doctor took ultrasound to be sure and blood work. The ultrasound just showed follicles in my ovaries. Nothing abnormal and blood work is negative. I had my daughter may 5th and Im worried.

I have a blood disorder and i don’t want to end up in the hospital again. Doctor gave me provera in hopes that my period will come back within a week or so and i am terrified that my period still won’t come even after they give me provera.
