"i have been on loestrin for 4 months now. i will admit the first month was kind of rough with the mood swings and headaches but once my body got adjusted it was perfectly fine.  like other women on here i had horrible periods with pms.  now i barely even notice cramping.  it did add a lot to my bust though,  which i am not complaining about at all. i haven&#039;t noticed any other weight gain at all.  all in all after the adjustment period i had no issues at all and also convinced a friend to switch as well and she loves it."
