I've had an Iud in for a year and a half and within the last month, some strange symptoms have come up and frankly, my mind is reeling. The symptoms started toward the middle part of April: constantly thirsty, eating a little more, and being tired. But now, I've been craving veggies and tuna (I hate fish), every night my stomach feels like I have the butterflies and that puky feeling. I've gained weight, i'm constantly hungry. I've been eating like crazy. I feel like niagra falls because i'm peeing so much. But like like I said earlier, i'm on mirena and haven't had a period in a year.... Opinions!!
