A girl ovulates before she starts to bleed so then she can get pregnant but if you mean a grown woman who have never had her period I guess she could be pregnant if she started ovulating. The question I'm wondering is why she has never had her period if she's an adult. It takes about 3 days for the egg to get fertilized. The egg is available for about a day and the sperms can live up to 5 days inside the woman's body so that can be both before and after the intercourse.
....No it does not confirm that you are not pregnant although it is unlikely there have been cases where women still receive there menstrual....
A woman shows signs of being pregnant when she first misses her periods or when the periods are delayed.
They missed their periods.
If she never has periods and never ovulates, then no, she cannot get pregnant.
If a women is pregnant than she will miss all of her periods, until she gives birth. then she will have a period every 28 days like normal
Usually but not necessarily. Some women can have one or two periods after they become pregnant but it is somewhat rare. The best way to see if you are pregnant is to get a test.
not technically, but she can still experience vaginal bleeding
Some women say they are sore, other women experience soreness with periods.
no sometimes your body just likes a break
Women who are pregnant do not get periods. If you are pregnant and you are experiencing bleeding and/or cramping you should contact your Dr right away or go to the ER.
It is unlikely but it has happened
Normally women do not get their periods when they are pregnant but it can happen.. If you are irregular on a monthly basis then I wouldn't worry about it. Otherwise after your period ends take a test just to ease your mind..
