Does your luteal phase length change?

I’m certainly no expert, but I believe your luteal phase generally stays the same length. That is why it is important to know when you’ve ovulated rather than how long your cycle usually is.  The one month my ovulation was delayed by 3 days, my luteal phase stayed the same length and AF just started 3 days later.

Good luck for tomorrow!

LP should stay consistent each cycle and does not matter if you ovulate early or late. Goodluck!

I’ve seen a lot of people report very occasional blips with their luteal phase. I think it must be that it’s almost always in a narrow range, but it’s still theoretically possible to rarely have it be off for some reason.

How do you know when you ovulated? OPK? Temping? both? something else? It’s also possible that you miscalculated your O day – for instance, if you were only using OPK and not temping, you could have had an earlier LH spike and actually ovulated later than you expected, etc.

It’s also possible that you’re just getting a late implantation/slow hormone showing.

Only time will tell for certain. Hang in there.

My luteal phase is 15 days. I’ve had a couple cycles that I marked as 17 days, but going back, I marked my temp shift 2 days early.

That being said, my FP can really vary. Normally I ovulate around cd17, last cycle I ovulated on cd23, and this cycle I ovulated on cd11. Last cycle, my period came after a 15 day LP, just as expected, and I had a 37 day cycle.

Depending on which ovary is releasing an egg, I have a longer/ shorter FP accordingly. It’s very interesting!

Best of luck!

Hmm given the variation in ovulation are you certain you ovulated? Maybe you geared up to and didn’t? I really don’t know much about US confirming ovulation so bear with me if that’s dumb.

From what I know it is supposed to be fairly consistent, mine isn’t though which is frustrating. Going to my specialist Tuesday to start clomid so I will be sure to ask!

My LP would be about the same give or take 2 days and was normally around the 11 day mark. My O day would change with more of a variance but my LP was more consistent.

I had luteal phase defect….our teaching couplenoticed it and my doctor confirmed it. Can be a few causes. Both thought low progesterone (which will cause you to not get pregnant or miscarry once pregnant). So I got pregnant but had lot progesterone. I did the suppositories but then it went lower, so then I did injecctions

See if you can see a NaPro dr.
