I have been on YAZ for about 1 year now and I have noticed several bad side effects. About 2 days before my period, I develop a SEVERE headache that increases in pain when exposed to light and sound. Therefore, I am bed ridden for the whole day, and unable to work. Which is 1 sick day a month that I HAVE to use.
I have also gained about 10 lbs over the past year and have remained active and eaten healthy.
I have a decreased sex drive and extreme mood swings.
If I miss 1 pill, or try to skip the placebo week (as I did on the week of my wedding)...I bleed for a full month...so much for the honeymoon!
I have been on birth control since I was 15 years old for medical reasons, and never had a problem until my doctor moved me onto YAZ to help clear up some skin problems (which it has actually done)
I will be switching to a new kind when my appt comes around in February.
