I am diagnosed with irregular periods . can i take metformin/ clomid (clomiphene) to treat irregular periods but i don't want to conceive now.is there any side ef?

Not clomid (clomiphene): If you have irregular periods, metformin may help. But we don't prescribe Clomid (clomiphene) unless someone is trying to conceive. There are risks to taking fertility meds for many months. If you are trying to avoid pregnancy then you may want to consider a combination of metformin and a birth control pill. If you are specifically trying to avoid birth control pills, then you may consider an iud or condoms.

Bad idea: You can maybe take metformin. Clomid (clomiphene) is for ovulation induction only, not regulating periods. It's not about side effects, it's not an appropriate drug.

Irregular periods: Clomid (clomiphene) and metformin are usually reserved for women with polycystic ovary syndrome, absent period who want to conceive. From your presentation, none of these scenarios is clear. If you are able to ovulate, then you probably don't need either of those medications. To get your periods regular without conceiving, i'd go for hormonal contraceptives first.
