Dizzy spells 2 weeks PP

I'll be 3 weeks PP C-section Sunday but since the 12th of this week I've been having lots of dizzy spells on and off through out the day. I'm still taking parentals and my normal vitamins so I would be okay.

I'm still bleeding period like on and off.

Had my 2 week check up with my OB on Tuesday the 11th the day before this started and I was fine.

I'm not sure what this could be.
