Hugs! I know I already replied on the other board.
It's probably your period. Because your hormones are all out of whack, you can spot through the first half of your cycle (I had that happen to me for a couple of months after my first m/c). You can also end up with a shorter LP.
I'd say you probably O'd and the progesterone stabilized everything for a couple of weeks and now you are getting AF.
It's been a while since my D&C (1st m/c only) -- so I can't remember when the bleeding stopped and physical normalcy resumed. Sorry.
But what I do remember echoes exactly what Aurora (militarybaby) said : in my case, after each m/c I had weird bleeding and strange periods for just a few months. Before the D & C, my ob/gyn told me to expect that because (in his words) "your body has just gone through a traumatic and unusual experience. So your periods will be weird for a while, because it takes a while for the body to right itself." That made a lot of sense to me.
So if it seems strange even for a little while yet, I'm sure that it's just natural. When my body resumed having a regular cycle pattern again, it was obvious to me. I'm guessing it will be obvious to you too.
I'm glad you've written. It's a very healing thing to do. We care.
