A growing body of research is pointing to a problem that sits at the intersection of medicine, psychology and social media: some women are stopping birth control not only because of the pill’s pharmacological side effects, but because expectations, fear and distrust may be intensifying how those effects are felt and interpreted. Psychologists at the University of Sheffield say this is consistent with the “nocebo effect”, in which negative expectations about a treatment contribute to real, distressing symptoms and a greater likelihood that those symptoms will be blamed on the medicine itself.
The issue has drawn attention at a time when oral contraceptive use in England has been falling and abortion numbers in England and Wales have risen to their highest recorded level. University of Sheffield researchers, citing NHS Digital figures, said prescriptions for oral contraceptives fell from 7.2 million in 2012 to just over 6 million a decade later. Separately, official government statistics published in January said there were 277,970 abortions for residents of England and Wales in 2023, up 11% on the previous year and the highest number since the Abortion Act was introduced.
At the centre of the latest debate is a 2025 study by Lorna Reid and Rebecca Webster, published in Perspectives on Sexual and Reproductive Health. The researchers surveyed 275 women aged 18 to 45 in the UK who had used the pill within the previous 18 months. The study found that increased expectations of side effects, stronger beliefs that medicines are harmful or overused, greater perceived sensitivity to medicines and lower trust in medicine development were all associated with a higher tendency to attribute symptoms to oral contraceptives. Higher side-effect attribution scores were also linked to discontinuation.
The findings do not argue that the pill has no real side effects. Rather, they suggest that some symptoms may be amplified or interpreted through a psychological lens that is shaped before a woman even begins treatment. The University of Sheffield said almost every participant in the study, 97%, reported at least one side effect. Over the 18-month period, 54.2% continued using oral contraception, while 45.8% stopped. Of those who stopped, 42 switched to an alternative form of contraception.
Webster said the pill gets “a lot of negative attention” and that researchers wanted to understand whether those views were affecting women’s experiences of oral contraception. She said “the side effects are very real”, but asked whether some might also have a psychological component, creating scope for interventions that could help women cope with them. Lead author Reid said acknowledging that some experiences may be shaped by the nocebo effect could help women make more informed decisions, especially younger women who may be more exposed to negative messaging online.
That online environment is an important part of the story. Search results for “the pill” on TikTok and other platforms are saturated with personal testimonies about bloating, low mood, acne, migraines, dizziness and weight changes. Some women describe feeling better after coming off hormonal contraception. Others say they felt more like themselves once they stopped. Those experiences are often sincere, but researchers and clinicians say the scale and emotional power of such posts can create a distorted impression of risk, particularly when dramatic stories spread faster than neutral or positive experiences. In comments published by The Independent, Webster said “negative personal stories” tend to be more compelling and more widely circulated than balanced information about risks and benefits.
The challenge for doctors is that many of the symptoms commonly linked to the pill are non-specific. Headaches, fatigue, nausea, anxiety, low mood and acne are all common complaints in the general population and can fluctuate for many reasons. That does not make women’s experiences imaginary. It does, however, make causation harder to establish. Webster said it is difficult to distinguish whether symptoms were caused by the pill or happened coincidentally, adding that psychological factors “may themselves generate or amplify symptom experience and attribution.”
The wider concern is what happens when women stop using a relatively effective contraceptive method and move to a less reliable one, or to no contraception at all. NHS guidance says the combined pill and progestogen-only pill are 91% effective with typical use and over 99% effective with perfect use. The same NHS guidance estimates natural family planning is 76% effective with typical use. In other words, a method promoted online as more natural and less invasive can carry a substantially greater real-world risk of pregnancy if not used with precision.
That shift has already shown up in research on abortion patients. A study in BMJ Sexual & Reproductive Health found a move away from more reliable hormonal contraception to less reliable fertility-awareness-based methods among women requesting abortions in England and Wales. According to reporting on the study and the journal summary, the share of abortion patients reporting hormonal contraception at conception fell from 18.8% in 2018 to 11.3% in 2023, while use of fertility-awareness methods rose from 0.4% to 2.5%. The researchers concluded that significantly fewer abortion patients were using effective contraception around conception and more were reporting no contraception or less reliable methods.
That does not mean social media alone is responsible. The distrust around hormonal contraception has deeper roots. Birth control has long been criticised for limited innovation, uneven counselling and the sense among many patients that side effects are brushed aside. The Sheffield researchers themselves framed their findings as preliminary and stressed the need for broader, more diverse studies. Their sample was predominantly young and White, which limits how far the results can be generalised. Even so, the study points to something many women and clinicians already recognise: expectations, previous experiences and cultural messaging matter in medicine, and they may matter particularly strongly in reproductive healthcare.
The result is a difficult balancing act. On one side is the risk of dismissing genuine suffering by suggesting that symptoms are psychological. On the other is the risk of allowing fear, anecdote and algorithm-driven misinformation to narrow women’s choices and push them toward less effective contraception. The Sheffield team argued that nocebo-related factors are potentially amenable to psychological interventions, which could reduce unnecessary discontinuation. That points toward a more careful response than either blind reassurance or outright scepticism: better counselling, clearer information, more honest discussions about uncertainty and more serious investment in contraceptive research.
For now, the evidence suggests that the story is not simply that young women are rejecting the pill, nor that they are wrong to worry about it. It is that concerns about contraception are being shaped in real time by a powerful mix of lived experience, distrust, poor public understanding and online amplification. When that happens, a medicine that remains highly effective for many users can start to feel dangerous before it is even taken. And once that expectation takes hold, researchers say, it may become part of the treatment experience itself.
