 [ Symptoms ] when is it safe to do heavy lifting and play contact sports after being infected with mono  i was infected with mono about 4 weeks ago i am training to enter a police force and need to do vigorous workouts and my doctor has not been very revealing about when i can safely go back to working out [ Disease ] hi found this on this site<link> its about all i can find doing research on it there is more on site just copy into google to the www to open and read our data show that a combination of metformin and contraceptive pill may be more effective in suppressing the hyperandrogenemia of obese and non obese pcos patients than metformin alone and may reduce insulin levels more than contraceptive pill alone hence combined treatment may become a more effective therapeutic option for pcos so what its saying isit would not harm the bc pills is this for weight loss hope it helps you good luck
