"this is the absolute worst birth control you could possibly take. i was on ocella for one month before i had to switch pharmacies due to my new insurance and ocella was fine. once i started on zarah, i had constant anxiety/palpitations. it got so bad to the point that i was seeing my doctor and thinking that i had a heart problem (had an echo done, normal). this birth control literally made me feel like i was going crazy and that i had all kinds of health problems. it made my left hand tingle, and i was also constantly exhausted to the point where i was almost sleeping 20 hours a day. oh and my blood pressure sky rocketed. went off this birth control and got the skyla iud. i didn&#039;t get pregnant on this bc which is literally the only good thing"
