At 32, Her Periods Stopped: The Fertility Clue Hidden in a Rented Flat

She was 32 when her periods stopped.

By then, she had already spent years on the Depo contraceptive injection. Like many women, she had been given a method that made everyday life easier, but nobody had helped her build a clear picture of what her natural cycle had been doing before it was suppressed—or what should be checked if it did not return as expected.

Then she met her husband to be. They moved into a rented flat and began imagining the next part of their life together.

She stopped the injections and started waiting for a period – it didn’t come as expected, not this month, not in the months after.
Initially they became irregular then lighter, than didn’t appear for 6 months and never came back.

Within a year of both moving in to the rented flat and coming of DEPO her menstrual cycle disappeared. It is worth commenting on that. DEPO is a medroxyprogesterone, which is a progestine, positioned as similar to “a natural hormone made in the body called progesterone”, but in reality chemical structure and action is more like testosterone. The key action is suppressing GnRH/LH/FSH signaling, which is used in contraception, but as compared to a natural cycle this suppression is not cyclical anymore rather permanent. Plus synthetic progestins vary and may also interact with androgen, glucocorticoid, or mineralocorticoid receptors, which explains differences in side-effect profiles. Being on DEPO created vulnerabilities that were triggered further.

The detail that did not look like a fertility detail

The flat had mould.

At the time, neither of them understood that the indoor air in the building could be relevant to her health. They did not know that she appeared to be super sensitive to mould exposure (estimated 10-25% of people are genetically predisposed and yes this can be measured), or that the change in her cycle and the change in her environment were just like oil and fire.

This is one of the problems with complex fertility cases. The important clues are often filed under the separate headings:

• A rented flat is a housing issue.
• A missing period is a hormonal issue.
• A history of Depo is disregarded altogether
• A thin endometrium is “an IVF issue”.

But the body does not organise its history into separate clinic departments.

My theory: years of DEPO have disrupted communication between the pituitary gland and the ovaries, while exposure to neuroactive mycotoxins have further compromised this delicate hormonal signalling. As a result, when natural menstrual cycling should have resumed, the body was no longer able to restore it effectively. With ongoing exposure and dysfunction, the situation have progressively deteriorated. So, what could have been done differently? That is really the biggest question. Unfortunately, by the time I see people, the situation is often far more complex and much harder to reverse. Ideally, she should have sought support from someone like me when she came off DEPO. I would have focused on restoring the natural pulsatile signalling between the hypothalamus, pituitary gland and ovaries, while also investigating and addressing mould exposure in their home environment.

But there is little value in dwelling on what could or should have happened. We cannot change the past. This is where we are now, and we have to work with the situation as it stands.

By the time she came to me

This was no longer an early fertility-planning conversation.

She and her husband had moved into donor-egg treatment. An embryo had been created, but another problem remained: her endometrial lining was not responding as they needed it to for transfer.

There is a painful assumption hidden inside this stage of treatment—that once the egg has been replaced, the principal problem has been removed.

But a donor egg does not bypass the woman receiving the embryo. Her endometrium, immune environment, circulation, inflammatory load and wider health still form the landscape in which implantation has to take place.

The question was no longer only, “Why did her periods stop?”

It was also, “Why is the uterine environment struggling to respond now?”

We went back to the timeline

We looked at the sequence rather than one isolated result:

• long-term menstrual suppression with Depo;
• the move into a mould-affected property;
• the loss of her cycle within months;
• her individual sensitivity to that exposure;
• and the later difficulty developing an adequate endometrial lining.

We worked on reducing her mycotoxin burden and supporting the systems involved in elimination and recovery. This was not a quick “detox”, and it was not based on the promise that one intervention would restore everything that had been lost.

Her periods did not return.

That matters. A responsible case story should tell you what did not happen as clearly as it tells you what did.

But something clinically important did change: when she prepared for embryo transfer, her endometrium began to grow.

For this couple, that was the immediate barrier they needed to move.

What the story shows is why chronology matters.

When a major symptom begins after a major environmental change, that detail should not be discarded simply because it sits outside the usual fertility checklist. And when donor eggs are introduced, investigation of the person carrying the pregnancy should not stop.

This is what complex cases keep showing me: a fertility outcome may depend on a clue that is often overlooked.

If your cycle changed and never properly returned

Start with asking yourself the following questions:

• What was my cycle like before hormonal contraception?
• Why was that contraception originally prescribed?
• Were heavy bleeding, pain, acne or irregular cycles already present?
• What happened after I stopped it?
• Did the change coincide with a move, illness, major stressor or environmental exposure?
• If I am preparing for transfer, has the investigation considered me as well as the embryo?

The aim is gather potentially important information and create a coherent detailed timeline.

If your periods have stopped, your lining repeatedly fails to develop, or your fertility history changed after a significant environmental exposure, you can book an Introductory Fertility Review. We will start with the full timeline and decide what genuinely deserves further investigation.
