A woman being pregnant for the first time or having a baby for the first time.
yes.
Probably not. I mean a woman's body is able to have a baby normally if it has regular menstruation cycles. You can check with your doctor. Though having a baby at that age will have heaps of psychological effects, mind you. A lot of responsibility!!!
is it she is having a baby
It is actually having a baby out of wedlock which basically means that you are having a baby without being married.
1/10 depends on the condition of the woman
it means your mom is having another baby or more
Nope, no sperm no baby.
Abortion, adoption, or having you baby and keeping it
Yes...
It depends on the family and friends of the woman having her fifth baby whether they want to have another baby shower for her. There is no set etiquette for this so a woman can have one or many baby showers for each child.
It probably means that the baby was hungry.
