Spotting after mc

Sorry if TMI,

I had a mc about 2 weeks ago. I had a couple of positive pregnancy tests on Tuesday, had first hCG taken on Wednesday. By Friday I was bleeding and Saturday i got my period. I was only about 5 days late on my period. I stopped bleeding after about a week. I had a few days with no bleeding and now I started spotting again. I don't have anything in my underwear, but I was charting CM and noticed pinkish tinge. A few times it was slight pink when I wiped Should I be concerned? I'm getting nervous as the spotting is getting slightly more. Please help! Thank you.
