Hi!!
Im not going to say you arent pregnant but gaging at another baby throwing up isnt really an indicator.
I think if it is your child throwing up you just deal with it. If its another child you get to see and smell how gross it is
I was fine changing my 8month olds nappy but then i changed my 2 year old neices pooey nappy and was dry reaching but i can change my 2 years pooey nappy now.
Oh and when my neice sneezed and snot was everywhere i was nearly puking when cleaning it up but if it was Haidyn im fine with it.

No idea how early is too early to get symptoms... Good luck getting the outcome you want tho!!!
