Ok so ladies I'm on the copper iud and this week my period is really weird! Spotty and light idk I'm worried I could be pregnant?? I know the chances are super rare but I've never had this and I've had it for almost a year! I'm calling my ob tomorrow for a professional opinion. What do you ladies think? 😥
