Funmi stopped the pill in January and expected her period to return within weeks. Six months later, nothing had returned. The investigation revealed mild prolactin elevation — treatable with one medication — and her cycle returned within 8 weeks.
Graduate student, Akoka. Presented with 6 months without periods after stopping the combined oral contraceptive pill (COCP) which she had used for 2 years. Multiple negative pregnancy tests. Mildly elevated prolactin on first panel.
Post-Pill Secondary Amenorrhoea (Hypothalamic Suppression)Funmi had been told by her GP when she stopped the pill: "Give it a few months." Three months passed. Then four. She was taking a pregnancy test every three weeks — all negative. At month five, she started researching "post-pill infertility" online. The results were not reassuring.
She came to Mascot Healthcare in July, six months after stopping the pill. She was convinced something was permanently wrong. The doctor asked careful questions: had she had regular periods before the pill? (No — 35–45 day cycles.) Had she noticed any breast discharge? (A small amount, once, when she pressed firmly.)
A targeted blood panel came back with a key finding: prolactin was mildly elevated at 850 mIU/L (normal < 600). This was the missing piece.
Post-pill amenorrhoea affects a small percentage of women — particularly those who had irregular periods before starting hormonal contraception. Investigation is warranted after 3 months without a period.
Complete absence of menstruation for 6 months after COCP cessation.
Periods were 35–45 days apart before starting the pill — suggesting pre-existing HPO axis irregularity.
Six home pregnancy tests over 6 months — all negative.
Occasional breast tenderness and mild galactorrhoea (milky discharge) on firm pressure — hint of elevated prolactin.
Increasing anxiety about whether she would be able to conceive in the future.
Repeated home pregnancy tests — appropriate; all negative.
Continued waiting based on "give it time" advice — reasonable to 3 months; investigation is indicated at 6 months.
Herbal fertility supplements — no evidence base for restoring ovulation in this context.
Blood panel: LH 4.2 IU/L (low-normal), FSH 5.1 IU/L (normal), oestradiol 148 pmol/L (low-normal), prolactin 850 mIU/L (mildly elevated), TSH 2.1 mIU/L (normal), HCG negative. MRI brain was discussed but deferred — mild isolated hyperprolactinaemia without headache or visual symptoms is commonly physiological or a microadenoma that rarely requires imaging initially.
A medication was started to reduce her prolactin levels. Funmi was counselled on the cause: prolactin suppresses GnRH, the hormone that kicks off the ovulatory cycle. Lowering prolactin allows GnRH to resume its normal pulsatile pattern.
Follow-up prolactin was checked at 4 weeks, showing a fall to 410 mIU/L.
Post-Pill Secondary Amenorrhoea with Mild Hyperprolactinaemia (prolactin 850 mIU/L; other hormone axes normal)
A twice-weekly medication to lower prolactin; repeat prolactin at 4 and 8 weeks; cycle tracking; period returned at week 8 of treatment
Prolactin normalised by week 6. Period returned at week 8. Cycles now 30–34 days — more regular than pre-pill. MRI brain planned if prolactin re-elevates.
Funmi's period returned 8 weeks after starting the medication. Her cycles are now more regular than they were before the pill. She remains on a low-dose maintenance regimen while monitoring prolactin.
Post-pill amenorrhoea beyond 3 months warrants investigation rather than extended watchful waiting. It is usually not the pill itself causing the problem — the pill often unmasks pre-existing hormonal irregularity.
Mild hyperprolactinaemia is a common, treatable cause of missed periods. Cabergoline is safe, effective, and usually produces results within weeks.
If your period doesn't return within 3 months of stopping the pill — get tested. Post-pill amenorrhoea has treatable causes.
