Dizzy spells?

Hi ladies, recently gave birth about a week and a day ago, today I woke up extremely dizzy, I didn’t even stand up, I was lying in bed and felt the room spinning and it was like this for about 15 minutes until I went to the restroom...

I’m still bleeding and the last day I’ve had clots not bigger than a quarter but more than usual..

Is this normal or could it be something else?
