STYLETHREAD -- LET'S TALK SHOP!

That sucks Cricket!  It's not uncommon to have really wonky cycles after a miscarriage, so you're not alone (I know that doesn't really help anything).  It can take some people's cycles up to a year after being off the pill to regulate themselves again (and sometimes they are permanently different than pre-pill cycles), so your body is still probably trying to sort itself out.  FWIW, my cycles are and have always been 28 days long.  That is until I started skipping periods using the pill.  It went great for a year and then the pill I was taking got too expensive so I switched to something else.  Though it was supposed to, it didn't suppress my period and I've had weird mid-cycle (or entire cycle) spotting ever since.  Looks like things are getting back to normal now since I stopped skipping periods.  Have you asked your doctore about your irregular cycles?

Hope things work for you really soon! 

Some none-of-my-business questions that you can feel free to ignore:

If you are temping/charting you should be able to determine whether or not the longer cycles are affecting the time of month you ovulate.  If ovulation isn't affected, the longer cycles aren't really bad you just have fewer chances per year technically to get pregnant.  On the other hand, if you had short luteal phases in the past the longer cycles could actually be good for implantation.
