hiii mam, Very good morning to healthcare magic forum. I am Dr Soumen Patra and try to solve your problem sothat you can take right decision.You have a 6yr old baby and presently you are not able to conceive. So you are suffering from SECONDARY INFERTILITY You also have irregular period.Lets start a wide discussion on IRREGULAR PERIOD & PREGNANCY **Irregular periods refers to a change in regular menstrual periods or menses. Mostly it ranges anywhere from 21 to 35 days. Every woman usually has a certain cycle length that is rather constant but sometimes varies 1-2 days per month. Remember that the onset of menses for every 35 days (regularly) is not considered as irregular menstrual cycle. However, irregular periods can be either of short term or long-term irregularity. **CAUSES: The irregular cycle is mostly related to stresses, tension, ingested medications and caffeine, a substance that disrupt corpus luteum function or even act as anticoagulant blood thinner. Cigarette smoking is another reason for abnormal cycles because it shortens the follicular phase. It also shortens the luteal phase if smoking is heavy. However, extreme alcohol intake is also a reason. **OTHER CAUSES: significant weight gain or loss, over-exercise, breastfeeding, PCOS/estrogen dominance, malnutrition, medications, chemotherapy, eating disorders, hormonal imbalance, recent childbirth, miscarriage or uterine abnormalities (fibroids/cysts/polyps/endometriosis). The occasional skipped menses cycle is not the only symptom of this problem. However, continued abnormality in period is also an indication of irregular ovulation and irregular menstruation cycle. **TREATMENT: As irregular menstrual cycle is treated according to the cause, it is determined with a blood test, ultrasound and biopsy. Often hormonal imbalance will be the major cause for irregular periods, which can be treated with appropriate drugs or hormones. Surgical removal of polyps or fibroids may also be done, if required. Treatment for irregular periods is also based on your plan for children. If you decide to have pregnancy, then a hormonal contraceptive or supplement will be prescribed to regulate your menstrual cycles. Never get tense regarding slight change or variation in your regular menstrual period. More than 50 percent of healthy women have the problem of Irregular menstrual cycle. However, consult your gynecologist if you are always with abnormal menstrual cycle. **First you have to regulate your period and proper timing of sexual intercourse is also necessary.
