"i started taking this birth control, and on the 8th day i had a anxiety attack (something i have never had or experienced in my life) however i was under a lot of stress so that could of been the reason to.  since you start this pill on the first day of your period, my bleeding lasted 10 days.  once i got into the second month, on the 3rd row (only 3 weeks later) i got another period that also lasted about 10-11 days.  in my third pack i got my period 36 days later , and i&#039;ve been bleeding for 16 days straight, the bleeding just never stopped i ended up having to contact my gyno to switch to another pill.  also had acne which was new to me.  only good thing was no weight gain."
