Hoping for the best

Hi im courtney im 21 260 pounds i have hypothyroidism and this was the reason causing me to faint/passout. That's how I found out I had hypothyroidism. Before I stared my meds/diagnosed. I had my cycle and it was starting to be constant since 2021. Now sice iv been on my meds no cycle. My cervix is high and soft and closed, and i feel pressure in my uterus but bfn. I don't know what's going on if I am pregnant, I would be almost 8 weeks now. Any advice?
