yes. when you have your period, your body is producing eggs ready for reproduction after menstruation. for someone to continue this process is not normal and they should get it checked out
Yes
When she is on her period ;)
A girl can get pregnant on any day of her 28-day cycle, even on her period.
It depends how often you change your clothes, or (if you're a girl) you're on your period, (if so, probably every day) but i suggest at least once every couple of days.
A girl can get pregnant any day if she's not using protection.
daily.
on day 14 of your cycle
You have your period a fixed 14 days after you ovulate. So if a woman has her period every 21 days, she ovulates on 21-14=7...the 7th day after the 1st day of her period.
yes a girl can get pregnant when she has her period...thats how majority of persons who cannot conceive succeed by having sex on their "day" .
