There is no chance. If your period was on it means that there is no way that you could have been ovulating. Don't worry.
If you missed a period and aren't using effective birth control, pregnancy is the most likely explanation.
About a 5% chance.
You're not pregnant. Same thing happened to me :) im 16. Biggest scare of my life but no you're not pregnant.
when a person is having unprotected sex, the chances of becoming pregnant are 100%, no matter what the regulation of periods or ovulation dates are.
id say unlikely... the menstrual cycle (when you would get pregnant) is BEFORE your period.
You can still get pregnant from pre-ejaculation. And on your period or not, you can still get pregnant.
Once you stop taking the birth control pills you are able to become pregnant.
It means your period is five days late. Only you know your chances of being pregnant.
good chances go see a doctor
You can get pregnant at any time of the month. But right after your period you have a less chance of getting pregnant, and right before your period because the egg needs to be in the tubes to be fertilized so if its the day before your period its not in the tubes.
very unlikely if you was pregnant whilst bleeding heavy the chances are you will miscarry but you can get pregnant whilost bleeding so you could in turn be pregnant but you would have had to concieve during your period which the chances arent very high but as i know from plenty of experience anything is possible when it comes to pregnancy
