is it normal for the wriggling and flutters to decrease at this point? they only really started about 10 days ago and last week they were really frequent but I was on holiday whereas I'm back at work this week so I don't know if maybe that's why the movements are so much less? (basically just a few flutters once or twice a day as opposed to lots all day last week). I don't want to worry unnecessarily but it's my first and I don't want to leave something if it is unusual. thanks.
