Ive had 7 and my ms varied with each of them

#1, moderate ms.........girl
#2, mild ms............boy (although this sounds like an indicator it isnt)
#3, moderate ms.........girl
#4, mild ms..............girl
#5, milder ms.........girl
#6, milder ms...........girl
#7, moderate ms......boy

so as you can see every pregnancy is its own and isnt an indicator of the sex of the baby.........well it wasnt in my experience anyway
