Women can be distrustful of their men at the best of times.
But if you reckon you’re under suspicion without good grounds, you might find the answer to your partner’s qualms in the medicine cabinet.
A study claims sex hormones in the contraceptive Pill bring out the green-eyed monster, making a woman more possessive and more likely to fret about her husband or boyfriend’s fidelity.
Those taking brands with the highest levels of oestrogen may even find their hormone-driven suspicions place their relationship in jeopardy, researchers warned.
The finding is one in a long line of ‘emotional’ side-effects attributed to the Pill, which is taken by some 3.5million British women – a quarter of all 16 to 49-year-olds.
The drug is also credited with making women broody, changing their taste in men and even boosting intelligence.
Working with Dutch psychologists, Stirling University’s Dr Craig Roberts asked 275 women a series of questions designed to gauge how much they trusted their partner.
Topics covered included how they feel when their other half flirts with another woman, whether they were worried that he would leave them for another woman and how possessive they were.
