Hi, I also turned 27 weeks last Tuesday. Ive been finding some days I have a lot of movement and other days not so much. At first I was a bit worried but I've come to think that is normal for me. As long as I still feel movements throughout the day I'm not letting myself worry. I think if you have 10 to 15 movements a day that's quite good. I was told if I worried to have a hot or cold drink and lye on my side for 30 mins I would probably feel movements.
The baby is fine when they are in a growth spurt they slow in movement then regain it. I am 27 weeks tomorrow and my daughter does the same thing its nothing to worry for
I am also in my 27th week and am experiencing the same thing. He is particularly wiggly today while I sit and wait for my sugar test.
