How does luteal phase works?

Hi ladies

Can anyone help me work this one out? My period range from 25 to 32 days with an average of 29 days so is it possible to ovulate at any time or does it work out from 14 days from the start of your period?

For example, is it possible for me to ovulate late like day 21 or 23 and still have a period on day 29? or ovulate early like day 11? Im very confused so I would appreciate a bit of clarification and no I haven't used any Opks test, I just test by cervical mucous.

Hi lovely. You need a lute up phase of around 10/11 days so to ovulate and for implantation to happen more than 10/11 days before a period... ( normally)
Give this lady a follow on Instagram- she has very useful easy to understand info about it all x

The only way to accurately check your cycles in through taking your basal body temperature. My cycles range from 27 to 36 days. I have a 15-16 day luteal phase so can ovulate any time between CD12 and CD19.

Once you know your luteal phase it generally stays the same give or take a day. Ideally you want this over 10 days.

They say that ovulation is around 14 days from the start of your period, based on an average 28 day cycle, but this really can vary from woman to woman. My cycles last 30 days on average and I usually ovulate around day 16/17 making my luteal phase 13/14 days long. As PP has said the only way of knowing is to check your basal body temperature to track your cycle.

12-14 days is the average LP length but you get outliers with very short ones (like me, 7/8 days) or very long ones (up to 18 days). The fact your cycle varies suggests your ovulation day changes slightly each month, but within normal ranges. I think it's pretty unusual for someone to ovulate on the same day every cycle.

Apps like Clue and Glo and Flo predict ovulation in the middle of your average cycle length. It's only coincidental if they're accurate. You might typically ovulate on the earlier side and have a long LP, or on the later side and have a short LP. The only way to know is to use OPKs and track BBT.

People say you need your LP to be at least 10 days but actually LP defect hasn't been found to be a stand alone cause of infertility, and the NHS won't treat it. I've seen people with 8/9 day LPs get pregnant. That said, if you have a short LP and haven't got pregnant after quite a few cycles I think it is worth treating, you just have to do it privately.
