Hello, I've been taking Mefenamic acid tablets for period pains on and off for a few years. However I've just found out recently on the Internet that taking this tablet can affect ovulation and even fertility. Has anyone taken them before? I've been trying for 3 months, so I know it's still early days, but I'm just wondering whether this could be the reason I'm not falling pregnant even though I track my ovulation and use ovulation kit.
