<s>[INST] Should I start birth control pills again to regulate my periods after a miscarriage? I have had irregular periods since the miscarriage 2 months ago, and want to get pregnant as soon as possible. I am 37 years old.The Doctor I spoke to adviced me to start BCP again as I got pregnant as soon as I stopped the pills previously. Or should I just continue to try to get pregnant with irregular periods? [/INST] You have not provided with certain necessary information like your BMI, whether your periods were regular before miscarriage while not on birth control pills. Now since 2 months your cycles are irregular.  Since you are keen to get pregnant, If I were your doctor I would not advise you to take birth control pills. I will wait for one more month. If you were cycles remain irregular will investigate after one month to find out the cause and treat accordingly. </s>
