The short explanation
You are not imagining it. Some women notice mood changes or lower sex drive on the combined pill. These effects are not universal, and studies give mixed results, but they are reported often enough that doctors take them seriously. If you notice these changes, talk to your doctor rather than just stopping. Options may include trying a different pill, adjusting how it is used, or switching to another treatment for PCOS. Low mood can also have other causes, so it is worth discussing how you have been feeling overall.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Tracking your mood and sex drive for a couple of months can help you and your doctor see whether they link to starting the pill.
- Vaginal dryness, relationship stress, tiredness and PCOS itself can also affect sex drive.
- If you stop the pill, your PCOS symptoms may return, so it helps to plan an alternative.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell whether the pill is causing your symptoms. Your doctor can review your history and options.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Could the pill be affecting my mood and sex drive?
- Would a different pill or treatment suit me better?
- What happens to my PCOS if I stop?
- Could something else be causing how I feel?
