On same pill for long time...recently have strange occurance

[karriwhel]

I have been taking Kariva (generic of Mircette) for about 5 years now. In the last 6-8 months every so often I go a month without a period. I have not skipped pills but every other month no period. This is the first time in all my experience to have had this happen with any bc. I have been clockwork down to the day with periods until now. I am slowly approaching 30yrs old and am wondering if anyone has experience this, if it has anything to do w/ age or body just getting use to the drug or drug perhaps not working as well....no more stress than usual lately either.

Let me know what you think & thanks in advance for your replies!

well i'm 37 now and i have noticed that my menstral cycle has really changed over the years. it isn't at all like it was when i was younger. another thing is maybe the bc might have something to do with it as you know it is mainly hormones. well if you don't get the answeres your seeking then by all means consult your doctor. well good luck!!!
