Why haven't I gotten my periods post PCOD treatment?

It is common to worry when your first sexual intercourse is not on time. It may be a bit late due to stress, weight gain hormonal imbalance, etc. If you think that you might be pregnant then do a pregnancy test to calm down yourself. Remember that every time one should use a condom during sex to avoid pregnancy and getting infections like HIV. 

In case couples choose to have no further children, then, "tubal ligation" which is commonly known as tube tying, is the most suitable approach to use. This process is successful and risk-free. However, when tubal ligation cannot occur maybe probably or fails, then, your partner can opt for vasectomy. Vasectomy is a brief surgical procedure that blocks the sperm from reaching into the semen hence no chances of causing pregnancy to a woman. After either of these two techniques has been done, none of them can be turned back to its normal state, so make up your mind about them wisely.

An abnormal vaginal bleed after menopause could indicate the presence of uterine cancer or endometrial hyperplasia and hormonal imbalance. I recommend that your mother consult a gynecologist immediately. A gynecological oncologist is a specialist who can diagnose her in more detail and prescribe treatment if necessary.
