I had no morning sickness and I'm having a boy (although I never get tummy sick in general anyway, thankfully) , however my cousin had no morning sickness and she had a girl. My baby's fathers mum had terrible sickness every day of her pregnancy with both her boys and my nan had no sickness with any of her children except the twins she was carrying (one boy and one girl), her other children were 4 boys and 3 girls.
I suspect it's just random as to whether you get morning sickness or not although it is fun looking out for symptoms that appear in either boys/girls
I had hardly any MS with my son. Had a girl pregnancy (sadly miscarried just before 12 weeks due to disability) but i was sick as a dog. Am pregnant again and it's exactly the same as the last, so assuming another girl.
I had average morning sickness with my daughter then it was horrendous with my son. I'm now expecting our 3rd and sickness has been average again. sex of this one is still unknown at the moment. all 3 are my husbands . x
