Hi, I'm having a problem 2 years ago I used to get my period twice a month, nd it stopped and it went back to normal for almost a year but months ago?

Abnormal periods. The answer to why women have abnormal periods can be tricky. Depending upon your age, you menstrual periods occurring two times per month is hormone balance related. However, there may be growths within the uterus that can lead to the same issue. We can evaluate hormone levels, and look inside the uterus with a telescope to obtain a tissue sample.
