<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi doc, I was wondering if Althea birth control pills could increase my cup size? Or should I take Diane for that? Also, I heard that birth control pills increases a woman s risk of never getting pregnant. I don t want to get pregnant now but someday I would love to have kids. Is this information true or is it a myth? Thanks!  <response>: Hello, Certain birth control pill which contain combination of both estrogen progesterone, more likely cause increased breast size in women with some other side effects. Though, increased breast size is not a permanent side effect of it and in most of the cases, breast size returns to normal after stop taking the pill or switch to a low dosage birth control pill contains only progesterone. In general, full fertility comes back within 1-3 months after discontinuing the birth control pill, and it totally depends on commencement of normal regular period. Hope, this information is very much sufficient to clear your doubt confusion. Be well take care.
