Confused?

Autumn • Mommy to Bentley, and Rylee Ann on her way. ❤️
I had a miscarriage around 5 weeks, last Thursday. I stopped bleeding 100% from it on Sunday and also took pregnancy test on Monday to make sure my HCG levels dropped and it was negative so then today (Wednesday), I wake up & went to the bathroom and was spotting. Is this my period or is it just leftover from the miscarriage? Anyone else have the same thing? I'm just confused.
