A shortage of contraception is causing chaos and risks unplanned pregnancies and abortions, doctors are warning.
Leading sexual health experts have written to ministers warning that the supply shortage is beginning to lead to serious problems across the UK.
A number of daily pills and a long-acting injectable contraceptive are thought to be affected.
The problem follows a shortage of hormone replacement therapy for menopausal women last year.
But there are signs that those supply difficulties might soon start to be resolved as a key ingredient is now being manufactured again.
It is currently unclear what has caused the contraception shortages.
Drug firm Pfizer first reported supply problems with Sayana Press, which provides three months’ protection and can be self-administered by women, last year.
It is the only self-injectable contraceptive on the market and is also used to help women control period-related problems, such as heavy bleeding.
The Faculty of Sexual and Reproductive Healthcare said there were also now shortages of a number of daily pills, including Noriday, Norimin and Synphase.
