I wanted to offer some input into your chart....
I would say that you almost certainly ovulated on CD26. I suspect that FF is getting confused (moving your CHs, making them dotted) because of the seemingly inconsistent CM reporting. Are the days where CM is blank days that you didn't notice any or days where you didn't pay attention/record?
Also, regarding your idea of a LP defect... Based on o'ing on CD26, I don't think that brown spotting on 10DPO is something that you should be stressing over.
Good luck, hun! I'm rooting for you!
Re: **Peetie** (ticker in siggy)
Thanks Leah. Yeah, I haven't been so good with recording CM. I can never make my mind up on which one it actually is. Then it was pretty much non existant for awhile.
CM can be tricky... I always operated under the philosophy that I didn't have to be right, just consistent.
Good luck!
