Weird period after back to back loss

I had a miscarriage on August 10th and then again September 19th. I tracked with ovulation tests after my first loss and ovulated 3 weeks later. I didn’t track this time because it was too draining. But now I’m wishing I would have because I don’t understand what’s happening. Last Sunday (so a little over 3 weeks after my miscarriage) I started spotting. It’s went from brown to pink. There was once a string of red blood mixed with discharge but that’s it. It’s not there every time I wipe either. I’m kind of assuming it’s a weird period. But I was anticipating a really heavy and miserable period since it was my first one after back to back loss. And weird that it came so early. What do you think? Should I be worried?

*Test is from 4 days ago. Thinking of retesting to be sure*
