So I lost 20 pounds for my upcoming wedding and have been living off of yogurt, fruits, salads, lean meats, tons of water and tons of veggies for the past 6 months. I just started to take birth cntr pills, about 3 weeks in and I am gaining weight!!!!!!! I noticed it today when I woke up and my pants are just a bit tighter and my barely closed! I am so scared that in 3 more weeks i will gain more. what can i do? any suggestions? has this happened to anyone?
