After my first my period was back about 3 months post partum and I conceived (but miscarried) about 10 months post partum. My second is now 10 months old and I've had nothing! I don't particularly want a 3rd right now (or maybe at all) but I find it odd that it's so different between the two. I've dropped more weight more quickly with my second so I wonder if that's it. What's everyone else's experience been?
