I had mirena put in about 8 months ago. everything was normal and good until last month. I started dieting and exercising to lose weight, ate healthy small portions, counted calories, i walk 4-5 miles a day and instead of losing weight i am gaining. my hair is starting to fall out, i get horrible headaches, i have missed 2 periods, i took 3 pregnancy tests and they all came out negative. i get car sick everytime i get in the car and get sick when i smell or see certain foods just like when i was pregnant. i have a dr appointment next week but i was just wondering if this may have something to do with mirena? oh and i also take my temps every morning and chart and my temps have been in the 98's for 2 weeks now instead of the usual 97's. any thoughts?
