Ok, upfront apologies for TMI.

I had a c-sect almost 5 weeks ago. For the past week and a bit I haven't been bleeding as such but more spotting and was mostly watery - very little blood appearing at all. For the past week I have been feeling a little crampy (similar to AF) on and off. Then this afternoon I went to the loo and noticed some bright red blood on my liner and it was there when I wiped the few following times I went to the loo. It seems to have stopped again now though... So, my question is;

a) Is this normal? To almost stop bleeding then start again...
b) To have AF so soon after birth?
c) COULD this be AF?

TIA
