Hi I hope someone can help me, OK so I started my period last wed. and on sun I was almost finishing my period so I decided to have unprotected sex on sun and mon. and I was wondering if its possible to get pregnant since me and my boyfriend are trying to have a baby. I wanted to know what my chances of getting pregnant were.

It's an urban legend that you absolutely can't get pregnant during your period. Because a woman's cycle is not 100% predictable, there is never a perfectly safe period as far as pregnancy goes.

Your cycle starts with an egg being released from your egg sac and heading down the fallopian tube into the uterus. There it waits to get fertilized by a sperm and turn into a baby. If no sperm comes along the egg and the uterus lining flushes away through your vagina aka your period. Then a new egg is released from your egg sac and the cycle starts all over again.

Obviously having sperm enter your uterus while the lining is being flushed isn't the best time for pregnancy. Since there isn't a uterine lining waiting for the new baby and there isn't necessarily an egg waiting there to be impregnated. However, a woman's cycle isn't always that nice and steady (especially for teenagers and young adults). The body can and does release eggs at odd times. There could very easily be another egg coming down the tube that is just waiting for a sperm, and the new baby (! ) could be there, waiting, when the next lining is formed for it.

Also, sperm are very hearty. Healthy sperm can easily last 5 days or more. So they can simply sit there in the uterus, waiting for the next egg to come down the chute. When it does, they hook up with it, create the baby, and now you're pregnant!

While the chance is a lot lower than doing on the best times, yes there is a chance
