Hello this is my first pregnancy and I'm currently 15+3, last nignt whilst I was try to sleep o noticed some strange feeling in my lower belly, it almost felt like a butterfly fluttering around inside of me and lasted about 30 seconds probably about twice, could this be the baby moving already? I wasn't expecting anything until later weeks as this is my first but sonographer did comment on how much baby was moving and being difficult to keep still at 12 week scan?
