A mother-of-three has revealed that she had two surprise pregnancies despite having the contraceptive coil fitted. Katie McKenn, a hairstylist from Manchester, shared her story in a viral TikTok video. McKenn’s first coil was defective, which prompted her to get it refitted. However, she later discovered that she was pregnant with twins. Despite the rarity of coil failures, McKenn’s story has sparked a discussion about the effectiveness of contraceptive devices and the importance of seeking medical advice if you have any concerns.
