Since I am breastfeeding still, I can't really depend on the tender breats as a sign
, but I've had other signs. I did have my period right after getting the Mirena, for like almost a month!! Then no period at all since. I like that part, but I don't like the loss of appetite, then cravings, then heavy mood swings, plus fatigue and definite loss of sex-drive. I too took a HPT which came up negative. I was relieved, but am now starting to worry as I am reading the rest of these.
