Help please!

C • Recently suffered a miscarriage. Trying to bounce back from it. Hopefully will have my rainbow baby soon! :)

All right, so I had a mc 3 weeks ago and my hormone levels are all back to normal, or supposed to be anyway, and my period should've shown up yesterday. I've had sore boobs for about a week now. I'm having problems with sleep. I'm urinating frequently.

Is it possible that I may be pregnant again? Or is it something else? Any help would be much appreciated! 😁
