A new survey has revealed that women are not entirely trusting of hormonal contraception.
Researchers for Schering-Plough found that more than three quarters of women who use hormonal contraception have concerns about their birth control method.
Nearly half of the respondents (46 per cent) said that they often felt relieved when their period arrived and one in five admitted that they sometimes had difficulty remembering to take their pill.
Dr Mary Jane Minkin, clinical professor of obstetrics and gynaecology at Yale University School of Medicine, described the lack of confidence in contraceptive methods as "very troubling".
"It only takes one birth control slip up to get pregnant, and if women are not feeling confident in their current method, they should express their concerns with their healthcare providers to find an option that suits them better," she advised.
The survey also found that, despite widespread concerns about the effectiveness of their contraceptive method, 39 per cent of respondents had continued to use the same method for five years or more.
A recent study in Scotland found that many women do not take the contraceptive pill because they are concerned about putting on weight.
