"the doctor put me on this to regulate my period. i&#039;ve never taken any birth control prior to this. i took it for 2 days and started noticing a strange sensation in my chest. not painful but uncomfortable as if i was not getting enough oxygen. i know it was the aviane because i have never had that feeling before. i stopped taking it, and i am very disappointed that i reacted that way because i wanted my breasts to get bigger and my periods to get normal. the doctor switched me to norethindrone because she suspects that i have an allergy to estrogen.
