Why do womens have period?

Each month, from the age of about 12, a woman releases one egg each month. If this egg is fertilised by sperm during sex, a baby is made. If it isn't fertilised, it starts to break down and the body needs to get rid of it. Also, during the month, the lining of the woman's uterus/womb starts to build up and thicken so that if the egg is fertilised it will be able to implant into the lining and grow. If the egg is not fertilised, the body also needs to get rid of this built-up lining. So, once the egg has been released, and not fertilised it will start to break down and the remains leave the uterus through the cervix and out of the vagina. As the lining of the uterus starts to break down and detach, blood vessels are ruptured and this is where the blood comes from.


Why do girls bleed from there butts?

If you are referring to menstruation, they do not bleed from their 'butts'. The blood is the thickened lining of the uterus detaching and falling out. This happens once every month if the woman does not become pregnant as the Uterus lining grows to give a resting place for a fertilised egg to become a foetus and then a baby. If the egg is not fertilised by sperm following sex, the lining of the Uterus is not needed and is rejected by the body.


Is it true that 6 days after menstruation can detect if you are pregnant already?

No, that's not true at all. Six days after menstruation you wouldn't even be pregnant; even if you had ovulated directly after menstruation and the egg had been fertilised, it can still take up to 14 days for the fertilised egg to travel down the fallopian tubes to implant in the uterus. The soonest you can tell if you're pregnant is two weeks after you have sex.

Can you have pregnancy symptoms three days after sex and having brown discharge?

Three days after sex would be too early for most pregnancy symptoms to begin (eg. sickness, dizziness) however brown discharge could be a sign of implantation (where the fertilised egg implants in the uterus lining). I suggest taking a pregnancy test in 3 weeks time
