Hello and welcome to HCM.
Thank you for your query.
First of all, I would have liked to know your age, as women who are approaching
menopause, can experience many changes in their menstrual cycles, flow, breast and other changes. If you are around the 40 year age group, then this could be the explanation.
But, if not. Then the only other possibility could be a
hormonal change. Hormonal changes can occur at anytime, due to various reasons: peri-menopause,
thyroid disorders,
polycystic ovaries, etc. If you are diagnosed with any such condition that can cause a hormonal imbalance, then you need to go about an evaluation of the particular condition. Please visit your doctor for more insight on the cause.
I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications. I would gladly help you.
Best wishes.
