Fingers crossed that things start "working" again for you soon.

It can definitely differ after one child and the next, so hopefully this time it will come back quicker for you. AF returned after about 9-10 months for me after my first bub while he was still breastfeeding around the clock. Then after my second was born I was breastfeeding both of them so assumed it would take longer for AF to arrive. Well, 17 months later and I haven't had an AF yet... I have had another baby though, LOL! Turns out I must have ovulated when DD was 4-5 months old and we conceived a surprise baby before AF got a chance to show her face Hmmm, breastfeeding three kids now so it'll be interesting to see how long before AF comes back this time...
