Period after miscarriage - confused!

Jennifer
Hello. I got my BFP August 5. Doctor estimated me to be about 4 weeks. US only showed thickening uterus lining. Following week pregnant symptoms disappeared. Bleeding started August 16 and doctor confirmed mc on August 17. I took cytotec August 19 and bled until August 27. I started bleeding again August 28, this feels exactly like a period. From the bloating, cramping, and etc. I unfortunately lost the baby very early. This is my first mc. Could I possibly be having a period already? I'm confused bc I thought was not possible. Any ideas would be appreciated!!
