New study from Betsy Pleasants, Julia Ryan, Dr. Cassondra Marshall, and Dr. Ndola Prata finds people commonly wrote about contraceptive side effects and experiences using methods on r/birthcontrol, highlighting the value of r/birthcontrol as a space to post about aspects of contraceptive use that are not well addressed by clinical contraceptive counseling. The value of real-time, open-access data on contraceptive users’ interests is especially high given the shifting landscape of and increasing constraints on reproductive health care in the United States.
