Is this her first or second/third etc pregnancy? If it's the first, I would be surprised if she could feel anything at 14 weeks. If a subsequent one, then it's perfectly possible - in my second I felt movements from 12 weeks!
I felt the fluttering movements at about 15 weeks. Only way I could describe it was like having champagne bubbles floatting up the inside of your stomach. Not nice when you have morning sickness aswell!!
Now I am 38 weeks and have whole feet sticking out my left side with bruised ribs and muscles from a very active baby.
Do the flutters happen every day? I felt the champaine bubbles at around 15/16 weeks (first pregnancy so I can't say anything with great confidence). But now 17 weeks and I don't seem to feel them? may be I am trying to be alert all the time doesn';t help.
So shall i not worry and wait until the kicks start at 20 weeks?
