According to your symptoms (irregular cycles and periods), you might be experiencing the start of peri-menopause. When we consider your age (31), however, the possibility of menopause, although possible, is less likely. Menopause starts when you havenât had a menstruation for more than a year. Before that time, women can experience cycle irregularity. The period without menstruation is not longer than a year in these cases.
It is very important to distinguish if you are experiencing periods (menstruations) or another type of vaginal bleeding (metrorrhagia). You can visit your gynecologist to clear that up. A vaginal examination, vaginal ultrasound, Pap-test, and hormonal analyses (estrogen, progesterone, FSH and LH) could be necessary.
If your periods are simply not as heavy, it might not be menopause-related. I recommend visiting your obgyn if you continue to have these symptoms.
