I have a 5 year old son and expecting another baby boy which I really wanted.. the day i had my ultrasound and found out i was having a boy i was so excited but then yet i felt disappointed, sad kinda wanted to cry because i know my husband really wanted a little girl and was only choosing girls names before we found out the gender ... is it wrong to be feeling like this?
