"i have taken several different birth controls, and this is by far the best i have tried. my body is very sensitive to hormones. my doctor put me on yaz first and it was a nightmare. they switched me to lo-loestrin hoping to get rid of the migraines, mood changes, and weight changes. (yaz made me gain 8 lbs in less than 21 days- i&#039;m an avid runner and watch my diet very carefully. i was having to take 200 mg. of b6 just to get my wedding band off because i was retaining so much fluid) lo loestrin has been great. i immediately noticed a difference in fluid retention. i have had no bloating- no pms at all- didn&#039;t have a period either though. no acne, no mood swings, no migraines. i wish it wasn&#039;t so pricey."
