Luteal phase

co

For those of you that take ovulation tests is it always reliable for you to have a menstrual cycle 14 days after ovulation? I know that 14days for a luteal phase is standard, but I didn't know if it worked that way for everyone!

I have an irregular cycle, but actually had a positive ovulation test 13 days ago. My pregnancy tests have been negative, I was just seeing if having a positive ovulation test would help me predict when my next period (hopefully not though) would come.
