Hi I'm 5 months pregnant, I went from not feeling my baby at all to suddenly feeling her kick, move and wriggle, for the past week she's been very active, everytime I sat down she'd kick and kick, when I layed down to go to bed she'd kick and wriggle and when I woke up to go to the toilet at night and got back into bed she'd be very active, but last night she wasn't as active and this morning I only felt 2 kicks when i woke up and I haven't felt anything since :( this is my first ever pregnancy so I worry about everything should I be worried about this?
