Most people have come across Reddit threads where users claim “That pregnancy prevention pill made me gain weight,” often followed by heated back-and-forth debates — or seen X users posting, “IDK if I’ve gained weight, if it’s the pill, or if I’m pregnant.”
According to a statement in 2019 from The Faculty of Sexual & Reproductive Healthcare, there is a perception that weight gain is a common side effect of contraceptive use and this is often cited as a reason why women do not initiate or do not continue contraception.
