With the duration, probably not how, since every woman has her own cycle.
But with pain, I completely resolved this problem after switching to veganism, no, no, I do not campaign, but after studying such a plus, I realized that I began to follow almost all the points to eliminate pain, and they can be observed with a classic diet.
-Limit the consumption of sugar, salt, coffee, strong tea and do not exceed the required daily amount of liquid - 1.5 liters per day. Excess fluid in the body leads to painful swelling of the breasts and edema.
-Alcohol is also harmful. It increases hunger, headaches, irritability.
-Forget about foods containing artificial additives and flavors.
-Beware of large amounts of animal fats, as they are the main source of cholesterol, excess of which contributes to the violation of blood circulation processes.
-Substitute butter with vegetable oil. Do not limit yourself to fresh vegetables and fruits, as they contain the necessary vitamins, minerals, and fiber. By the way, vitamins of groups A and D improve skin condition and prevent the appearance of acne during PMS. And vitamin E eases painful sensations in the mammary glands and relieves depression.
Nutritionists advise to eat more plant foods and less meat for PMS. An excellent remedy for PMS is soy. The fact is that soy contains phytoestrogens, which help to cope with the rampage of hormones. Replace meat with fatty sea fish. Salmon, trout, tuna, sardines - all of these varieties contain unsaturated fats that will satisfy your fat needs during this period and are also very beneficial for heart health. And make it a rule to season vegetable salads with olive or vegetable oil.
If you don’t want to follow a diet before menstruation or not, then my mother was prescribed female dietary supplements and after a couple of months everything went away.
This (desired outcome) is a common side effect of oral contraceptive use. More precisely, against the background of their intake, it is not menstruation that passes, but a menstrual reaction. But if a girl does not need more or less regular protection, then using OK only to normalize her periods ... Option, of course, but this is if not just discomfort, but a direct diagnosis can be made. If you utter the terrible spell "hyperpolyalgomenorrhea", then it’s as if it’s understandable, sho treat - you have to go somewhere. And if you just want it to be shorter and without unpleasant sensations - so where to swallow pills! ..
In a word, about the option of pills - personally discuss with the gynecologist.
And so - yes, nettle is the most (normal strength: not weak, not steep, 3 r / d the day before and during menstruation), but antispasmodics, when it really hurts.
I will console you with the fact that most often it normalizes after the first birth. Well, that is, pain is the result of the uterus contracting, and the cervix does not open very much, allowing menstrual flow from the uterine cavity to go out. A certain discoordination. Hence the painful sensations: these are not very effective contractions of the uterus, and sometimes even at the same time, menstrual blood can be thrown through the tubes into the pelvic cavity - well, it irritates the peritoneum, sometimes even with appendicitis, etc. it is necessary to differentiate (exclude). - And after childbirth - and the uterus has matured, pumped, and everything is in order with the cervical canal)
Personally, I use a weak tincture of freshly boiled nettle (a tablespoon of leaves per liter of boiling water) - to liquefy clots that give pain or very concentrated - to stop (I use this extremely rarely - at sea, for example, it should not be overused))
