Explain to me in simple terms stuff like period, menstruation, ovulation, PMS, e!

It's really simple once you get the basic know-how.

Your period happens when an egg has died because it wasn't fertilized by a little spermy. This means it didn't attach to the wall of the uterus, so the uterus begins shedding some of its lining. Blood, the unfertilized egg, and some tissue leave through the vagina, creating a bloody mess. During this time some womens bodies go absolutely nuts and hurts all over -- especially in the back. You may get migraines and your breasts may be tender to touch. There's also constipation and bloating. And don't forget the cramps and PMS -- the evil twin duo.
PMS is Premenstrual Syndrome and women who have it can act like a tiger you just kicked in the stomach. Girls will be unhappy, tense, anxious, stressed, and have vicious mood swings.

Basically, after your period you go through another phase: ovulation. This is when an egg(s) is prepared in your body (if it is fertilized you get a baby) and during the peak you are most likely to get pregnant. So during this time many women say that they are much hornier and ready for some action.
Bad news for you though, it's hard as heck to get this time without a great deal of information about a girl's menstrual cycle. if her periods are irregular it may even be impossible sometimes. However, if you've been paying killer attention to a girl's cycle you can use an online calculator to find out when she's ovulating.

Period- this is when the blood and womb lining exit the body. During this time she will most likely have cramps, bloating and backaches. A period can also be called menstration.

Ovulation is when an egg is released, often the girl has an increase of vaginal discharge around this time.

Pms- this stands for pre menstural tension or syndrome. During this time a girl will become moody, get cramps backache etc

a girl can become horny anytime although I think that during her ovulation time she will be more horny.

every month the falopian tube releases an egg (ovulation) into the womb . if this egg is not fertilised, the lining of the womb comes away and is ejected from the body in the form of a period.(menstruation) PMS stands for pre menstrual stress, and this is where hormones are being released into the body just before this whole process begins. she is likely to feel irritable, in pain, and generally p!ssed off. try hitting on her now and shes likely to kill you slowly

you are sick. and should be ashamed of yourself for showing your sickness on line. if you really wanted to know you would go on wiki. no thanks.
