What are some things that have delayed your ovulation? I’m currently on CD21 and starting to question if it will happen this month.🤕

My cycles vary quite a lot, from 25 to 35, but mostly 31 days. I’m curious if anyone has noticed a pattern with what causes it for them, like stress, poor sleep, illness, travel, diet, etc? Or does it sometimes just happen for no real reason?

Would love to hear your experiences if you want to share.

I wonder if coming back to work and switching my daily rhythm has affected my ovulation, as I now got to bed early and wake up at 5:40 am, while for 4 weeks I was sleeping late and waking up late (10 am).

Have you observed some interesting patterns of what delays your ovulation?

I noticed Premom app says that roughly 47% of women have a rapid onset LH surge (under 24 hours) and roughly 53% of women have a gradual onset (more than 24 hours). However I think I stumbled upon the study they took their numbers from (without providing references), which has 3(three!) women! Which makes it extremely uncertain if these percentages are actually accurate. I am not aware of other studies, so if anyone knows more than me, please let me know!

I the meanwhile I thought we could have a poll here. I am going to edit this and copy the texts from Premom app to define these surges.

I am not sure about mine, because I used Clearblue digital advanced for a few months, but this time I am also doing OPK strips.

Do you have a rapid (less than 1 day) or gradual onset LH surge (more than 1 day)?

From Premom:

Gradual Onset > 1 Day Example This LH surge builds for multiple days, gradually increasing until it reaches it's peak, then gradually decreases. The test lines on your ovulation test will becoming darker until you reach peak day, where your test line will be darkest, and then quickly lighten from there.

Rapid Onset < 1 Day Example This LH surge can happen quickly, within a few hours. Women with rapid onset patterns may only detect one positive ovulation test, despite consecutive days of testing. In these cases, it is recommended that you test your LH levels twice daily, once in the morning and once in the afternoon to ensure you do not miss your LH peak.
