Thanks for query,
Yes exactly you have a menopausal symptoms.
Usually after 40's woman has hormonal
imbalance leads to menopausal symptoms in which there were no regular periods some times you have 20 days cycle or some times you have 120 days cycle.
If you have no other symptoms except irregularity you need not to worry but if you have excessive bleeding & prolonged bleeding then the possibility of fibroids should be ruled out by going for USG report.
