Estimates suggest more than half of women have suffered from the condition, called dysmenorrhoea, at some point.
The Scandinavian study, reported in the journal Human Reproduction, found women on the pill reported slightly less severe period pains.
Oral contraceptives are not currently officially licensed for this purpose.
The researchers, from Sahlgrenska Academy at Gothenburg University, followed groups of hundreds of 19-year-olds, recruiting some in 1981, some in 1991, and the rest in 2001.
Five years after an initial health questionnaire, the women were contacted again to see if anything had changed.
The Swedish researchers noted that younger women typically suffer more from painful periods than older women. And while they did find that symptoms eased somewhat with increasing age, the effects of age and Pill use were independent of each other and use of the Pill had a greater effect overall.
The study included three groups of women who turned 19 in 1981, 1991 and 2001. Each group included 400 to 520 women, who were asked about their pattern of menstruation and menstrual pain, reproductive history, contraceptive use, height and weight.
The women provided this information at ages 19 and 24.
"By comparing women at different ages, it was possible to demonstrate the influence of [the Pill] on the occurrence and severity of dysmenorrhea, at the same time taking into account possible changes due to increasing age," Dr. Ingela Lindh, of the Institute of Clinical Sciences, Sahlgrenska Academy at Gothenburg University, said in a journal news release. "We found there was a significant difference in the severity of dysmenorrhea depending on whether or not the women used combined oral contraceptives."
Dr. Steven Goldstein, an obstetrician/gynecologist at NYU Langone Medical Center in New York City, said: "The study results are not surprising. It's gratifying to see researchers documenting scientifically what practitioners have been seeing for a very long time. The amount of discomfort from a woman's period with a combination birth control pill is a fraction of what it is without the Pill. There is a diminution of pain from the Pill."
For her part, Wu believes that "doctors should include a discussion of all the benefits and risks when presenting birth control options, and the improvement of dysmenorrhea is a significant benefit to oral contraceptive pills.
