I am on this new birth control for a month and a half and noticed a decrease in libido? is there a supplement i can take to help with this?

Despite their claims, there is no supplement proven to increase libido, but evaluation is difficult because there are so many underlying causes. Birth control pills can decrease libido when they eliminate your monthly hormone fluctuations (your libido tends to increase when you are fertile). Regular exercise, stress reduction techniques, and attention to your relationship may all help.
