I agree that you should keep charting. It will be helpful to see if you ovulated again, if your temps are stabilizing, if your CM is getting back to normal. My first cycle post-m/c was pretty wacky. My temps stayed elevated for quite a while, and I had a lot more CM for a longer period of time. It was nice to know that I was ovulating pretty much as normal. And it will just keep you in the habit for the next cycle that you do TTC.
