Doctor's answer:
If the menstrual cycle has always been 45 days, as long as it is periodic, it is considered normal and medication is not needed. A longer menstrual cycle will result in a later ovulation, so ovulation should not occur on the 13th day of the menstrual cycle. Ultrasound dynamic monitoring can be used to track the development of follicles and ovulation to determine the specific ovulation time.
