Fainting 4 weeks PP?

So I fainted today. It came over me slow and started as a chest pain that built up and went into my head and I couldn't hear anything. Took me a while to get on my feet without being shaky and still feeling lingering chest pains/limb weakness.

Has anyone else experienced this? Am I nuts for not seeing a doctor?

I'm not a fainter normally but I also didn't want to drag three kids and my husband to urgent care or something.

I did message my doctor and won't hear back until tomorrow.

As a note it could be anemia since I had a class IV hemorrhage after c-section.

But I wanted to see if anyone else had anything to share that could keep me from worrying I made the wrong choice. Or if I'm being goofy, get the help I need.
