I think in my previous pregnancies I wouldn't have thought too much about this. But have been reading (on MN) about the 'Count the Kicks' campaign and it's made me very conscious of my baby's movements. Have been aware that last night there didn't seem to be any, and today, they're less than usual. So rang midwife and now have an appointment at 12 to go into the hospital for monitoring.
Of course, the baby seems to be moving a bit more all of a sudden now. But I'm going in anyway, think I need the reassurance. Fingers crossed!
