28.
put simply, what you saw in 28 days later applied to women, they enter a state of perpetual intense rage and begin spewing blood while attempting to rip shreds out of the uninfected (the men). luckily it does not contaminate on contact.
period infection stage -

"ahhhhhgtklhky!!!" *tear, rip, bite...gargle*

1. A period of pure agony for a female, lasting way too long. Signs of this state include screaming at anything that moves, rolling around on the couch in pain, and spending hours with cold water and stain remover.
2. A useful thing that ends a scentence, that does not exist for most l337 people.

Something I somewhat enjoy getting every month because its my body's way of letting me know I haven't gotten knocked up.

The most fucking annoying thing on Earth (except Crazy Frog).

No wonder they call it "the monthly curse".
Contrary to popular belief, you actually can have sex during your/your girlfriend's period. It's pretty gross for both parties, though, so I don't recommend it.

6.
When a woman sheds her uteras lining. Starts as early in soem girls as age 8 and as late as age 18. Happens about ever 28 days, could be more or less. Happens for 5-7 days. Could be less (lucky!) or more.
Basically when blood comes out of a womans vagina. Creates cramps and bloating.
I can't swim right now, I have my period.

7.
The time of the month when female hormones wage a bloody battle against said female. An unfertilized egg that had sauntered down from the ovaries through the falliopian tubes and been stood up by its date, sperm, and the lining of the uterus become the refugees of the battle, and flee through the vagina, and on to the poor female's panties. Sometimes though, the female loses her war-ravaged mind, and thinking she can stop the misery, shoves a wad of cotton up her twat. This, like many peace-keeping efforts, fails frequently.
It was a period of strife.
