How concerned should I be?

So here's the scoop, 2 months ago my doctor switched me from a tri-cyclen to a progestin only pill (Ortho Micronor). I started the new pills, as directed, on the first day of my period. However, about 10 days into the new pills I had my period again. Not just spotting, full on heavy period and then didn't have a period at all at the end of that month as I normally would. Naturally I attributed it to switching pills. Now I've about finished my second month and haven't had any bleeding whatsoever. My period is now about 4 days late. I know that the new birth control could easily have just whacked out my cycle, but just to be safe yesterday I went ahead and took a home pregnancy test, with a negative result. So now I'm just wondering if I should just relax and see if I get a period again sometime over the course of the next month, or if I should take another test. How long is it ok to go without a period, if I am in fact, not pregnant.

Thanks

The switch from a combination pill to a progestin only pill is a confusing factor for your body. My guess is that you will take a couple cycles to level off. It is still worth calling your prescriber and having a talk with the nurse. There may be variables of which I cannot be aware.

You did all the right things. And, I appreciate your helping make the point that "there are pills and there are pills;" not interchangeable.
