She did not make you puke or have an emotion like being mad at you or fussy. Babies in the womb are active or not, probably after a while they are beginning to form a sense of whether things are normal or not (such as, they can tell when you are pacing around or resting). But please, don't kid yourself that at 18 weeks that your baby has the power to fuss, make you do anything, or be angry.
She definitely didn't make you puke though haha that's just hormones or you ate something funny. :P
I'm sure they can be mad haha my girl moved away and did like a pushing motion it was so funny, the next scan she looked happier.
This is sad to think about but babies can actually cry in the womb too.
