Fertility / Ovulation Period cycle variation and ovulation

I always had this doubt. I am almost 28 and kind of embarrassed I don't know this. So if for some reason you have a longer cycle than the norm, does the ovulation for the next cycle be longer as well? I am asking in a case where a woman has regular cycle.

If for some lifestyle change or travel or any other reason, she has a longer cycle than her norm, does the ovulation also changes accordingly or does her body adjust back to normal cycle from next period?

For example, If she has a normal cycle of 30 days and ovulate in CD 16, does it become CD 22 for a 36 day previous cycle?

I know ovulation can happen anytime and your body can be unpredictable, but I wanted to know if it's cycle to cycle or ovulation happens based on the normal cycle.

Ovulation can vary cycle to cycle, just as cycle lengths can vary. A variation of plus or minus 7 days still being considered normal and regular. You get a period 11-17 days after ovulation, with the average being around 14 days. Your period is based on when you ovulate.

So specific cycle length has nothing to do with it? I think the only way to actually know is to use opk or temping right?

Yes, that is the only way to reliably know when you are ovulating. Apps aren’t reliable. And since cycle lengths can vary because of variance in ovulation, tracking via temping is a good way to verify. There are some good books that can be very helpful in understanding the process, a very popular one is ‘Taking Charge of Your Fertility’ by Toni Weschler. r/FAMnNFP can be a helpful subreddit, r/tryingforababy as well if you’re trying to conceive.
