Luteal phase change 7 to 12 days in 1 month?

[kasigirl]

ok ladies! for the last three months my luteal phase has been 7 days generally ovulating around cd 20 of a 28 day cycle. it looks like this month I ovulated on cd 15 or 16 if my cycle remains 28 days I will have jumped to a 12 day luteal phase. has anyone else seen this? a bit of background I stopped bc in september and this I is my 8th cycle trying.

Hi kasigirl
Just wanted to say that's ace! My LP is 8/9 days and has been in the last 3 cycles I've been charting. Before that I can only assume it was too, because I haven't taken the BCP for over 5 years. Would love to have a change like that myself! x

Thanks! I am still doubtful!
