I've read lotsof threads about ladies feeling flutters and even kick around 16-18 weeks and am bit worried that I'm now in my 21st week and have hardly felt anything. My placenta is in the posterior placenta, although it's lying a bit low - does this make a difference to when I should feel him/her ? I had a scan last Monday and so we know the baby is okay, hb was 155-160 and measuring right on date. I don't get why I've not felt anything yet !!!. Would appreciate your thoughts.
