I think it is classed as a period cos u can get pregnant again almost on the same day u give birth!!! (i may b over-reacting slightly!)
apparently, a woman is particularly fertile soon after she gives birth however, due to obvious reasons, u may not be up 4 any of the antics!
Good luck and I hope this helps
p.S. U r so sweet the way u talk about ur baby, you'll be a fab mom i'm sure :d
