Charting Question

[Mrs. JJ]

Hello ladies :wave:

I am confused by my chart from last cycle. FF insists that I ovulated on CD 20 so I was surprised when AF showed up much earlier than I expected. My LP is always 12-13 days but according to FF it was only 7 days. Is FF wrong? What's going on??

I believe you ovulated on CD18. You have a temp drop on CD20 that is probably tricking FF's computer.

That would still only give me a 9 day LP. Are there any reasons I would have a short LP like that?

 

[Mrs. JJ]

You are right though, If I get rid of that dip it puts me at CD18 for O. Still not sure what could cause a temporary short LP... makes me a little nervous...

I really dont know why your LP would change significantly. Hopefully it's nothing to worry about.
