I don't know what to think anymore

I had a D&C done September 16th. I was measuring 10 weeks but the baby stopped growing at 6. I bled for a couple days then had really light spotting for another week. I went to do blood work on October 14th and my HCG levels were still at 52. I started my period on the 18th. My doctor confirmed that that was my actual period because my levels were so low. On the 28th my levels were at 26. I started taking ovulation tests on November 1st because Glow said it was my fertile week. I watched the test be negative until the 4th were it came up positive. During those days of testing I started getting ewcm, which I always get when I'm ovulating. Well, My doctor just called me and said last Friday(14th) my levels were still at 5. I took a pregnancy test yesterday and it was the biggest bfn. Did I even ovulate?! I'm so heartbroken right now because now I don't even think there's a chance I could be pregnant!
