I thought I might find other topics already on here about it, but none specifically answer my question.

Ok, I started my cycle Wednesday the 23rd. Thursday me and my boyfriend had unprotected sex (we normally use the withdrawal method) and I let him ejaculate inside me. The reason behind this was I thought I'd heard that pregnancy is less likely when girls are on the rag.

Then today I heard that girls are actually MORE likely to get pregnant on the rag.

My brother told me it's like this: Normally without protected it's a pretty big risk. When you're on your period it's a lot more likely. When you ovulate it's almost a sure thing you'll get pregnant.

So which is it? Am I more or less likely to get pregnant while on my period?

And another question I had: If I DID get pregnant on my period would it continue to flow?

Bicycle? I prefer a homocycle.

Pregnancy takes about a week to occur in total, so yes were you to become pregnant your period would still continue. It is less likely you would become pregnant right before and during a period, but not impossible, because some women ovulate close to their periods. However, to be safe we always suggest using a reliable form of birth control every time if you don't wish to become pregnant.

You can get pregnant any time.

Okay, your brother is totally wrong.

Here's the basic facts:
- You are most likely to get pregnant around the time that you ovulate.
- Ovulation usually occurs between 10-16 days before your period starts.
- If ovulation occurs closer to your period than about 9 days, a fertilized egg generally won't have time to implant and cause the hormonal changes which allow a pregnancy to be sustained. Your period is an extremely reliable sign that you are not pregnant.
- Sperm can live 5-7 days in the vagina, especially around ovulation, when the uterine environment is, shall we say, "more welcoming."
- Therefore, whether or not sex on your period is less likely to result in pregnancy depends on the length of your cycle and the length of your period. If your cycle is 25 days long and your period is 7 days... yeah, that's a risk.
- When we say "you can get pregnant at any time", what we really mean is "it's close to impossible to tell in advance when the fertile part of your cycle is going to hit, so you can't assume you're safe."
- Even when the sperm and the egg are in the right place at the right time, this combination only results in pregnancy about 25% of the time.
- 25% is not "almost certain", but it is not a small risk. Over the course of a year, about 80% of heterosexual couples who have regular, unprotected intercourse will experience a pregnancy.
