Heavy Period Last Month, Late Period This Month: Is There a Link?

No direct causal link. A heavy period does not delay the next cycle. Cycle length is governed by the hypothalamic-pituitary-ovarian axis.

Possible Explanations for Late Period

• Pregnancy (test first).
• Anovulatory cycle (common with stress, weight change, PCOS, thyroid).
• Perimenopause (irregular cycles).
• Medication changes.
• Illness, travel, significant stress.

Action

1. Pregnancy test if >1 week late.
2. If negative and irregularity persists >3 cycles, see provider for hormonal evaluation.
