Hi everyone so I'm on my 4th pregnancy, my first son was born weighing 7lb 9oz then I had my daughter she was 7lb 12oz then my son and he was 7lb 2oz had to have extra scans as he showed smaller now pregnant with my 4th currently 17 weeks and 4 days and my bump is alot smaller then it has been in previous pregnancies had a private gender scan as I did with my son and comparing them this baby is showing smaller then my last son was for the same amount of weeks I'm also booked for a lot more scans this time every 2-3 weeks once I reach 30 weeks feeling a little worried ?
