18 weeks - Prenatal visit

I've made to 18 weeks. I should have a teeny party. I had a prenatal appointment today and all is well. Baby had a strong heartbeat and is pretty active. I swear s/he is stretching in there. Maybe it's trying to make some extra room in there or something. At least I'm definitely feeling movement. It's tapping and pushing and kicking gently. My hemoglobin is getting pretty low though and I've had to start taking iron suppliments to keep the level from dropping any further. No wonder I'm tired...
