Hi, thanks for asking in Healthcare Magic. Your menstrual problem may be due to Poly Cystic Ovarian Disease (PCOD). It is due to hormonal imbalance and is characterized by irregular periods, anovulatory cycles, increased androgen production, disturbances in thyroid function and insulin resistance. Glyciphage is Metformin given to improve insulin action. M2tone is a herbal preparation also given in PCOD. M2 tone is claimed to induce ovulation. Metformin also stimulates ovulation by improving estrogen action in addition to its action on insulin. Ovulation means release of egg from ovum. This egg fuses with the sperm, forms zygote and gets implanted (attached) in uterus and develops in to fetus. Failure in ovulation will delay your conception. Since both Metformin and M2tone stimulates ovulation your chances of pregnancy will improve on taking these drugs. Also, you have to take them regularly to conceive. Stopping them will delay your chances of conception. I hope this is useful to you.
