2 cycles ago, I had a 34 day cycle. I think I did O, but we missed it (NTNP anyway).
1 cycle ago (actively TTC) , I did not O because my entire cycle was only 14 days long.
So, this current cycle comes along and I had no clue whether it would be 34 days long again or 14 days long.

I am on CD17 and I see blood. red blood.
You are reading a post on spotting, so here's my TMI:

-it is red
-there is not much (I peed some out, and there was a good amount on the bathroom tissue
-there was *nothing* on the tampon I wore all day
-no cramping like a period

Last time I saw blood, it was 11am. It is now 9pm and nothing all day.
Would you say I am on CD17 or CD1?

P.S: For the last 2 days, I've had VERY ALMOST positive OPKs.
