Hi, I have been taking levlen ed for about 4 years, but recently my doctor got me to try microgynon 20 ed to see if it would have an effect on the frequency of my headaches (which I have been getting for 12 years, long before the pill). I have been taking the microgynon for almost 2 months and it hasn't seemed to make any difference so I wanted to switch back to levlen at the end of this pack (its way cheaper

).
Is it ok to switch back so soon? If it is ok, will I be fully protected the whole time I am switching? Also can I just switch straight to the active pills, skipping my period?
Thanks muchly, any advice is greatly appreciated!
