Hi, iv been on the rigevidon pill for about 1 year. When I recently went to the doctors for another 6 months of the pill subscription I was given microgynon 30. I was told by a friend that they are basically the same and she had been given both in the past. I did 1 pack of the new pills and felt no change, I am on my second pack now and I'm really not feeling great. I feel nauseous, dizzy, my whole body aches. Is this because of the pill? Should I change to the old one?
