Detailed Answer:
Hello
I understand you wish to if pill Mononessa regulates hormone.
Yes. This is a contraceptive pill containing estrogen and progesterone which regulated hormones and there by brings about periods in women whose cycles are irregular.
Let me tell you that this hormone is not for long term regulation or permanent regulation of periods . This can only help as long as you are on this pill. But you cannot get pregnant while on this pill.
Hence if you have frequent irregular periods, this pill is not answer. You should check if you have polycystic ovaries and also check if you are overweight as the treatment differs in such cases.
