Any idea what’s going on?

I had a miscarriage on February 12th. I bled for 7 days and then stopped. I was keeping an eye on mucus to track ovulation and didn’t have fertile cm until 4-5 days after I would have ovulated in a regular cycle. When it started, I started opk’s and haven’t gotten a positive. Then for the last 2 days I have had light brown spotting. Is this the beginning of my next period and I didn’t ovulate? Did I ovulate early and this is implantation bleeding? I was so in tune with my body before my miscarriage and now I have no idea what’s going on. Any ideas would be appreciated! Thanks for reading this far.
