No. Having your period means that no fertilized egg implanted in the lining of your womb, and thus your body is flushing itself out in preparation for your next ovulation. I suggest http://www.woomb.org for more information on the menstrual cycle and fertility awareness.
If you've had a regular period, you are not pregnant. Don't confuse this with spotting which is a pinkish fluid that lightly "spots" in a pantyliner throughout the day. Spotting could possibly mean a pregnancy, or it just might mean your period is coming. To know for sure, have a pregnancy test done either with a home version or from the doctor.
Yes absolutely, but usually you will notice a difference in your period, such as it may be very light.
Yes, it is a possibility. If you are in doubt take a pregnancy test or consult a physician.
You could have gotten pregnant on your period
Not normally
yes
Yes.
No. If you still have you period, you cant be pregnant.
this means you are no longer pregnant. you were either not pregnant, or you have lost the baby.
If you had unprotected sex you could be pregnant, if you are still concerned take a test.
Even in the presence of bleeding, you could still be pregnant.
Not having your period but spotting is int unusual during pregnancy.
No you can't be pregnant and still have your period. You can have a light bleed but not a period. As for the whole negative test thing, it could be a false negative.
If you really had a miscarriage, you can't still be pregnant, but you could be pregnant again before you get your next period.
In some cases when you are first pregnant you can still menstrate but I don't know how common that is.
