I'm on the pill (desogestrel) if i take boots brand carb control, can it affect my pill? will i still have safe sex? or is there a risk of pregnancy?

Will not affect: It will not affect your birth control. These type of supplement generally do not lead to weight loss as advertised either.

Should not affect: The effectiveness should not be affected by a carb Control product but also remember that birth control pills are not 100% effective.... so if you want better effectiveness then an IUD would be better
