I am 48 years old, I used Triphasil birth control pills for years, but since the Clinic told me that Triphasil is not available anymore, but Trigestrel, I started to use Trigestrel. What I found is that it doesn t matter how healthy I eat, I am gaining weight. In the year and a half using Trigestrel, I gained about 10kg. I want to stop with Trigestrel, but do not know what to use. Could you please give me some advise. Thank you
