My period time chafed5/10 days usually&the medium is 34 days,isit irregular?i have sevral nabothian cyst max5millimeters in ovary bothsides,dangerous?

Unsure: I'm afraid I don't understand " chafed 5/10 days". An average cycle length of 34 days is within the normal range and some variation by a few days is also common. Nabothian cysts are not on the ovaries. They are inclusion cysts on the cervix. 5 mm. cysts on the ovaries can be normal follicles or can be a sign of PCOS depending on the number, appearance, timing in the cycle and other symptoms.
