It changes mainly when I start, stop, or switch birth control
It correlates with how hard I've been training and how well I'm fueling

It's fine unless the shifts were emotionally stressful too
Late or irregular-my sleep clock rules my timing
More affected when I recently changed contraception or meds
Mostly delayed when I also under-ate or skipped recovery

You recently started a new hormonal contraceptive. Which outcome sounds most familiar?
Stressful transition weeks seem to throw it later more than the method itself
Sleep schedule consistency decides whether it stabilizes quickly
Timing clearly shifted right after starting or switching methods
It went off-track when my training spiked or fueling dropped
undefined
You ramped up mileage for a race. What pattern shows up with your bleeding?
Hard weeks plus life stress tend to push bleeding later
Late nights and early runs disrupt my sleep and push it off
Changes happened mainly when I altered contraception or used EC
It tracks closely with whether I'm fueling enough and recovering
undefined
After an 8‑time‑zone flight, which influence feels strongest on your next period's timing?
The trip's stress level more than the clocks

A sudden breakup or emotional shock happened this month. Which effect fits best?
Bleeding often arrives later after big emotional waves
Only changed when my sleep got erratic too

Stress felt like the main driver of the delay
The circadian chaos obviously pushed ovulation later
No big changes unless I also missed pills or used EC
It lined up with my under-fueling during study crunch
undefined
You used emergency contraception this cycle. What best matches what happened next?
Stress around the situation seemed to delay bleeding most
My sleep was thrown off and that timing change stood out
The EC clearly shifted timing compared with my usual pattern
A tough training block plus light fueling matched the delay
undefined

Stress around the switch made timing wobble most
