i would test in a couple weeks just in case but i'm sure it's fine. breastfeeding does help but you can still ovulate
i was told an IUD (Merena) is a good one...i'll be doing that.
you can also take the Pill but it's a different formulation.
* the other reason they want you to wait is because of infection, you're uterus isn't healed up inside yet. where the placenta came off it's an open wound...another reason you bleed
