Good day!

I''ve been on Yaz for 6 months now, gained 4 km''s, my boobs went a cup size up and ever since it is sore. I''ve called my Gynea and she said that there is a couple of women complaing of weight gain and that Yaz is very surprised at all of the complaints. Is there anyone who experienced the same?
So now my gynae has put me on Melodene. Can anyone tell me pros and cons? How effective is it preventing pregnancy, keeping menstruating regular, amount of hormones vs yaz?

Thank you!
