Have You Ever Experienced Period Delays After Taking a Medication or Injection?

Many women notice changes in their menstrual cycle after starting certain medications, injections, or treatments.

:pill: Why does this happen?

  • Hormonal Medications/Injections (like contraceptives, steroids) can directly affect cycle regulation.

  • Antibiotics, Painkillers, or Other Drugs don’t usually cause delays, but the stress/illness for which they’re taken can.

  • Medical Treatments (for chronic illness, cancer, mental health) may indirectly alter hormonal balance.

:warning: When to take it seriously:

  • Delay is longer than 2–3 weeks without clear reason.

  • Repeated irregular cycles.

  • Other symptoms like severe pain, heavy bleeding, or unusual discharge.

:backhand_index_pointing_right: Menstrual health is closely tied to overall health so changes shouldn’t be ignored.

:speech_balloon: I’m curious have you ever experienced a period delay after taking a certain medication or injection? What was your experience like?

yes, i have experienced when i was diagnosed with kidney stones i was already on my periods and was given many injections of painkillers and what not to reduce the intensity of pain. soon after treatment the next month i saw delay of my periods for a week. I thought it is due to the medications and those painkiller injections.

I tried, but instead of a delay, I got my period earlier, and the gap between cycles was reduced. Now my cycle is normal again, with my period starting two days later each month instead of on a fixed date.

Yeah @dr_deepika even our mood swings get even worse due to the irregular cycle and heavy bleed.
