I keep wondering about mirena (I'm 38, no pregnancies and no plans for one - up until a couple years ago, my gyn wouldn't consider them for me, but I have a new doctor who actually listens to what I want
)
I don't know what Lybrel is so I'm looking it up....
However- I've been on oral contraceptives continually since 1994 (tri-phasics - generic now, but ortho-tricyclen before it went off-patent) For years in the early 2000s, I took them continually and skipped my periods - had occasional spotting (but I have that when I include the placebo/period week, so it didn't bother me over much)
I know from talking to my friends & colleagues & my doctors - most of whom have been on birth control pills at some point - is that different formulations affect us all differently. I've stayed on the same pill for ~20 years because it works for me and I don't have side effects - why mess with a good thing? So I'd say - try Lybrel and if it works for you, great^
