Period after "chemical" pregnancy?

Sarah

Sorry in advance if this is TMI. So this past week has been trying. I had a positive pregnancy test, started bleeding, went to the emergency room and I was told I had a "chemical" pregnancy all in the span of about 5 days... But that's just some background info. Anyways, I started what would be considered my period this past Thursday. It's Monday now and I should be on the last day of my period based on my previous cycles although I can understand if it's a bit different. However, I've still got a decent flow going on. It's still deep red in color and have passed some clots, the biggest was a bit bigger than a quarter... Is this normal?
