Sudden exhaustion?

I am about 32 weeks pregnant now.
Today was such a weird day for me. I've never felt so tired! I don't have the energy to do anything. This morning I was ok, but then all of a sudden I was just exhausted. I'm also having some really bad pain in my back. Is this sudden tiredness normal?

    My midwife said my iron level was normal.

      I would say it was normal for this far along. I would rest as much as you can because you will need it to store up energy for birth and life with a newborn.

        That makes sense. I find it a bit strange though because I am not very active. I can take naps, but I'm afraid it will be harder to fall asleep at night.
