Legs turning red occasionally

I’m almost 9 weeks postpartum after my second child. I’ve been experiencing instances where my body gets flushed / warm and my legs literally turn red. It goes away after a little bit but keeps happening once a day or once every few days. My feet also still have a little swelling at times. Has anyone else experienced this? Idk if it’s a hot flash bc my mom said she never had her legs change color during her hot flashes when she went through menopause. I feel like doctors say everything is normal after having a baby but it seems odd this hasn’t gone away yet. This never happened after my first was born. Feels like maybe my body can’t regulate my hormones at times. I’m also having random bleeding after my first period at 6 weeks. When I think it’s stopped bc there has been nothing for 36-48 hrs I start spotting again and have had an occasional gush of blood at times. I’ve been checked out and the labs they ran were normal.
