A woman's uterus contracts slightly in order to shed the lining (which is seen as "blood").  These contractions can be an annoyance to some, and very painful for others.  The discomfort is controllable by medication.

Almost all women have some cramping during their periods, classified as either primary dysmenorrhea (which refers to "normal" menstrual pain) or secondary dysmenorrhea (which is a result of an underlying disease or disorder).\n\n"Normal" cramps occur in almost all women due to the release of prostaglandins, which are hormones produced by the endometrium (the lining of the uterus). Prostaglandins cause the uterus to contract (sometimes quite painfully) in order to expel the menstrual debris (and henceforth, start the period). Some women produce higher levels of prostaglandins than others, so they may hurt more. \n\nHOWEVER, killer cramps are NOT normal and are in most cases due to secondary dysmenorrhea. Most frequently this is because of a disease or disorder like Endometriosis, Adenomyosis, Pelvic Inflammatory Disease, cervical stenosis, structural abnormalities in the vagina or uterus itself, fibroids, etc. If your cramping disables you, see your gyn to talk about options.\n\nNon-steroidal inflammatory drugs like aspirin and ibuprofen may help relieve cramping...your doc can also prescribe oral contraceptives that will prevent ovulation and reduce prostaglandin production, thereby alleviating cramping. \n\nUse of heating pads, avoidance of salt, sugar, alcohol and caffeine, intake of vitamin B6, calcium and magnesium supplements, and pelvic massage are all said to be helpful as well. \n\nIt is important to determine if the cramps are "normal," or if they could be due to another cause. Pain that is crippling is never normal and should be investigated ASAP so that appropriate diagnosis and treatment can be rendered. Hope that helps.

Depends how old you are. I took my teenage daughter to the doctor's as her periods are very irregular and he said it's normal at her age for them to be erratic. Perhaps you should visit your doctor and check there is nothing wrong? If the frequency and/or severity of your periods bother you, there is the option of going on a lose dose contraceptive pill to regulate your periods and reduce the pain. If it's only happened this once I really wouldn't worry. I've not heard of the weather affecting menstruation but apparently the moon can. I'd talk to your doctor if you're really worried if only to put your mind at rest x x

A lot of people retain water before their cycle begins. And, of course, when you retain water for a few days, at some point it has to be expelled from your body (hopefully!). So I imagine that's what the frequent bathroom visits are about.\n\nAs far as the pain, uncomfortable as it may be it sounds like normal cramping. Ibuprofen and a heating pad can help.

It could be caused by the intercourse it'self.\n   Your positon could be alot of the problem and it is causing a temporary change in your uterus position,hence the pain.\n    The pain usually subsides by it'self.

A lot of women have some sharp pains when they are ovulating which usually happens around the middle of your cycle.  This may be it.  It shouldn't be too bad or last for very long.  If it is I would consult a doctor.

Take some midol, wear a pad because tampons make cramps worse and get one of those heating pads to put on your back or stomach whichever hurts more.

You should have restarted having your periods by now and should not have pain instead of having a period.  Please see your doctor to get tested to determine what the cause may be.

It is also common to have sore breasts around the beginning of a girl's period, or menstruation. A week or so before her period starts, the body begins producing lots of the female hormones estrogen and progesterone. \n\nThese hormones can cause feelings that together are called premenstrual syndrome, or PMS. Some girls have painful cramps in their stomachs, headaches, mood swings, or cravings for certain foods right before their periods begin. During this time the body may retain water, which can make a girl feel puffy and bloated. Rings and shoes may feel tight at this time. \n\nJust as fingers and feet swell, so can breasts. All that fluid forces the breast tissues to expand, which stretches the nerves and makes breasts feel achy or tender. \n\nhttp://kidshealth.org/teen/sexual_health/girls/sore_breasts.html

If it's in the middle of your cycle, it could be when you are actually ovulating.  If so, the pain would be caused from the egg being released from the ovary.\n\nI guess my question to you is - does it happen every month?  \n\nGood luck!  (You may want to talk to your gynecologist.)

Yes, your body is trying to store up nutrients because you going to lose a lot once you start to flow.\n\nIf you have painful periods eat green leafy veggies like broccoli, cabbage, romaine lettuce, and collar greens.  It will lessen your flow and ease your pains.  It's the high amounts of natual vitamin Bs that do the trick. Pills won't work.
