change in luteal phase possible?

[gizmo77]

sorry im bad at explaining things :-(
the earliest ive O'd is cd17. latest cd 23. average is cd18

30-31 day cycles.

i assumed if LP s changed something was wrong bc everyone kept saying and ive always read LPs never change. rarely change.

Well, in the experiences that I have had (helping people on IG and here) everyone's LP is always changing by a day or two, or even more in the case of someone who had a very short LP and then took supps to lengthen it.

I still kinda suspect that it's more likely your O day is changing rather than your LP and your O symptoms are changing as a result of swaying, so it's confusing you on when you're actually Oing.

okay. see i thought my LP was fine at 13. and i know my O day is always changing (cd17-18) but based on the amount of ew, im assuming i O'd with a an increase in LP days (14 days verse the regular 13 days). but who knows really? temps arent relaible, cm isnt, opks arent. i need a personal ovulation predictor expert. or an ultra sound machine. ;-) thanks!

I am sorry, I went back and reread this and I had forgot you were just talking about a change in LP from 13 days to 14. (for some reason I had 5 days in my mind, I think because I was reading that you Oed between CD 17 and CD 23 with 30 or 31 day cycles (so that would put you with LPs that were changing by as much as 5 days). But a change in LP from 13 days to 14 is totally possible and happens quite commonly.

I corrected my other answer because I was not understanding what you were getting at. A change in LP from 13 days to 14 days between cycles is totally common and happens all the time.

My confusion was stemming from you saying you were ovulating anywhere from CD 17-CD 23 with 31 day cycles, which would put your LP changing as much as 5 days. In that case, it would be much more likely that O day was changing.

LP varying by one day - totally normal and happens all the time
LP varying by 5 days - your O day is probably what is really changing.

The only way to really know is an ultrasound machine but the good news is, you don't actually HAVE to know for sure. Just BD the next night after a pos OPK!

thank you, sorry for the confusion. i should have said in the last 7 mos that i have charted, the latest i O'd was cd23. the shortest was cd17. but even THOSE were ALL 13 day LPs. (i started with a long cycle, O'ing on cd23, just coming off of BF'ing. the other long cycle i had was with L-arginine). so typically O is cd17-18 with 30-31 day cycles.

thank you!

I gotcha!

I'm sure you know this already but long cycles after BFing are totally normal and we all know about l-arg!

Anyway I would not waste a moment's concern over the difference between 13 and 14 day LP, that is normal and can vary.
