Combination pills are the usual treatment given initially to correct irregular cycles and as far as side effects are known, hirsutism
is not seen with the pills; it is more likely to be due to the basic hormonal imbalance that is the cause of the irregular periods
. Please get a complete hormonal evaluation to rule out polycystic ovarian disease
and also get a sonogram-pelvic/trans-vaginal, to help in the diagnosis. Also, maintenance of a healthy weight and regular exercise is going to help you a lot. Hope this helps.
