I am currently using name brand Minivelle. My insurance only allows 1 box (8 patches) per calendar month. In beginning I was using Samples from GYN. Now that I have to get from pharmacy I have noticed that for Months with 31 days I don't have enough patches to stay on schedule. Not sure if Maybe switching to another 2 day option would help or what to do. I can't NOT have a patch on schedule. I get Horrible symptoms. Anyone have suggestions? I appreciate any help!!!
