Hi, Welcome to HCM. Microgest 100 g is usually prescribed to be taken once daily at bed time after having a filling meal, for HRT ( hormone replacement therapy ). It contains hormone progesterone that aids secretion of proteins and hormones needed to maintain pregnancy. If conception fails, endometrium sheds and menstruation occurs. Side effects are tenderness of breasts, abdominal pain, nausea, edema, headache, rash, depression, tiredness, liver problems, etc. When you are trying to conceive you should take much care of your spouse an your diet. Any therapy will not produce the desired results if nutritious diet is not taken. Protein, calcium rich diet should be taken. Include nuts, legumes, dairy products, veggies, fruits, berries and balance it with carbohydrate. Avoid any addiction, do not gain weight, have fitness tests done, take care.
