"i switched from a combined pill to nora-be about four months ago because the doctor said i couldn&#039;t take estrogen because of chest pain and migraines. the pill is 100% very effective and no mood swings, no migraines.  however, the bad side effects were excessive hair shedding i mean more than the normal, excessive bloating even without carb intake.  i also had cramping, hardly bleeding just spotting.  my period was never on time but can feel the symptoms of pms.  overall, pill is very effective but excessive hair loss!"
