Yes.
Pregnancy requires that semen (sperm) from the boy's penis gets into the girl's vagina.
A girl cannot get pregnant if the hymen is still intact. Penetration and ejaculation have to occur for pregnancy. A girl cannot get pregnant by sitting on a toilet seat or bathing in a tub.
Yes it is possible for the girl to get pregnant if during her period. Having un-protected sex can cause pregnancy. However the girl is most likely to become pregnant in between the end of her period until the start of it.
"Amenorrheic" means "pertaining to the suppression of menstruation other than during pregnancy".
The only way to stop a pregnancy safely on purpose is by having an abortion. A doctor helps her with that.

No, you can get morning sickness when expecting a boy or a girl. It is a myth that you only experience it with one or the other. It's the hormones that are released during pregnancy that cause morning sickness, and these are the same when the baby is a boy and when the baby is a girl
the sonologist can tell you about 12 weeks into your pregnancy at an ultrasound.
