Did u want a boy instead of a girl? ?
Sounds like u may have the baby blues. Just missing carrying a baby in ur tummy. Lots of women go Thur this phase it's normal. But be sure to talk to someone u trust abt it. It will help.if u feel that it's not getting better with time or its getting worse talk to ur doctor. They will help u.
Don't feel like this, it's god gift. If your child is healthy then you are blessed with it.
