Does it sound like I need more sleep?

I've been getting light head aches, I felt a little dizziness a few days ago but it went away quickly. I haven't slept much at all, I'm exhausted and I'm on my 3rd week postpartum, it was a c section delivery. My doctor said I had a hemoglobin of 10 after the delivery. Does it sound like I need more sleep? I've been real busy since my baby is in the NICU, I started visiting her daily since the first day I left the hospital. I've been getting about 5 or 6 hours of sleep as well
