I'm 20+1 with my second baby and have started feeling quite regular flutters. I had my 20 week scan this week and all looked good. However today I've hardly felt anything and I'm just wondering at what stage you're supposed to worry. There's been no regular pattern of movement yet and it has only started being noticeable at all in the last week or so.
Is it common for baby to go a bit quiet at this stage?
