birth control
"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'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."
