Hello,
two months ago I had to switch from the regular combination pill to the "mini pill" due to high blood pressure.
I've been on the generic of micronor for almost 8 weeks and I have gained weight, my breasts have enlarged, and I haven't had a period since (am going to take a pregnancy test soon).
I'm not sure what advice to give you, but you can get information on the mini pill at
www.Webmd.Org
best of luck. I hope you find some information. I'm also going to try and exercise more to see if it helps. Not sure what to do about the breast issue, though.
