Every mother is different and there is not a very definite time. In general, this time is related to the mother’s age, whether or not she is breastfeeding, the length of time she has been breastfeeding, and the recovery of ovarian function. Overall, mothers who are not breastfeeding will return to their normal period sooner than those who are breastfeeding. Women who do not breastfeed usually resume menstruation 6 to 10 weeks after delivery; those who breastfeed will have a corresponding delay in resuming menstruation, mostly 4 to 6 months after delivery. The resumption of menstruation after childbirth is related to whether or not the mother breastfeeds, the length of time she breastfeeds, her age and the ability of her ovaries to recover. Generally speaking, new mothers who do not breastfeed usually resume menstruation 6-10 weeks after delivery, and on average, ovulation resumes about 10 weeks after delivery. For new mothers who are breastfeeding, the return of menstruation is delayed, and in some cases, menstruation does not occur during breastfeeding. The body may ovulate before the resumption of menstruation, so even if you do not have a period, you must do a good job of protection, and if you have sex, you must do a good job of contraception. The time of the first period after childbirth is not very fixed, even after the resumption of menstruation, it may stop for a month or two or even longer, there is no regularity, it takes some time for the new mother to return to the normal menstrual cycle. A. Is it normal to have a large amount of most new mothers’ first postpartum period will be slightly more than the usual amount, bleeding time is slightly longer, the reasons may be: 1, after giving birth to a continuous ovulation caused by ovarian estrogen secretion too much, stimulating the endometrium to make it proliferate, so the bleeding will increase when shedding. If the menstruation gradually returns to normal later, treatment is generally not necessary. 2, mental factors, new mothers excessive exertion, tension, etc. can cause heavy menstruation. 3. Organic gynecological lesions, such as uterine fibroids, uterine polyps, etc. If the first postpartum menstrual bleeding continues to increase and the bleeding time is too long (more than 7 days or normal time before delivery), you should go to the hospital for further examination and treatment. Some new mothers have very little menstrual flow for the first time after childbirth, or even a little bit and then it’s over. There are many reasons for low menstrual flow after childbirth, mainly: 1, the new mother is weak or there is traumatic bleeding, such as postpartum hemorrhage. 2, uterine dysplasia, reduced response of the endometrium to ovarian hormone stimulation, or partial adhesion of the endometrium. 3.The influence of maternal psychological factors. New mothers may also experience amenorrhea if they are subjected to strong stimulation and shock. 4.Low menstrual flow can also be caused by breastfeeding, sudden climate change, rain and cold, and fatigue. In addition, if the mother suffers from some diseases, such as anemia, liver disease, diabetes, etc., as well as lack of vitamins, endocrine disorders and other reasons can also lead to low menstrual flow after delivery. Third, what is the reason for late recovery time The most common reasons for late menstruation after childbirth are long-term breastfeeding, slow recovery of ovarian and endocrine function, postpartum hemorrhage due to the Silhan’s syndrome, etc. Breastfeeding has a contraceptive effect because breastfeeding causes the hormones in the mother’s body to rise, which inhibits ovulation. The symptoms of Silhan’s syndrome include decreased secretion of hormones from the anterior pituitary gland, resulting in the absence of menstrual flow, as well as symptoms such as weight loss, indigestion, coldness, weakness, and atrophy of sexual organs. In addition, for mothers who have not had their periods return for a long time after giving birth, they should be alert to the possibility of getting pregnant again. Irregular menstruation is also considered normal Whether or not breastfeeding, usually the first few periods of new mothers after childbirth, the interval, the amount of the amount is not regular, but generally after a few times will return to normal. However, if the postpartum cycle is disrupted for a long time, it is necessary to consult a gynecologist because it may be caused by neuroendocrine dysfunction, organic lesions or medications. In general, in order to avoid abnormal menstruation after delivery, new mothers should pay attention to the maintenance and recovery of their bodies after delivery, and carry out self-conditioning according to their actual situation: 1, pay attention to keep a happy mood, avoid depression, frustration, emotional tension. 2. Pay attention to rest and avoid overexertion. 3, appropriate participation in activities, appropriate exercise. The first few menstrual periods after childbirth may appear different from the previous ones. But new mothers should not think that “abnormal” is “normal”, if long-term absence of menstruation, irregular cycles, too much or too little, thick menstrual blood, large and hard clots, you should go to the hospital in time to identify the specific causes and then do the corresponding treatment. What to pay attention to in terms of diet and living When the first postpartum period comes, the breastfeeding mother’s milk volume will generally decrease, and the quality of protein and fat contained in the milk will also change slightly, and the quality of milk will be affected. At this time, some babies may experience slight indigestion, but this is only a temporary phenomenon and will return to normal after the menstruation is over. Therefore, even during the period, the mother can still breastfeed her baby normally. In terms of hygiene, change sanitary napkins regularly, wash your pubic area with warm water, preferably take a shower instead of swimming, and wait for sex until you are out of your period. Keep your vulva, underwear and hygiene products clean. Ensure nutrition, pay attention to the combination of meat and vegetables to prevent iron deficiency. Eat more fish, lean meat, animal liver, blood and other foods that are rich in protein, contain a lot of iron and are easily absorbed by the body. Do not eat sour and spicy stimulating foods, such as chili, ginger and cold foods, and should not drink alcohol or coffee. New mothers should also keep a happy mood, prevent mood swings and pay attention to rest.
