hi. yesterday i had a shooting pain in what i can guess is my womb. ever since, when i lightly push in that area, it really hurts. about a week ago, i woke up to a metalic taste in my mouth. in the past two weeks i have also had thrush. also, lately my breasts have been very tender, sore and i could swear they are getting bigger. i have a mirena fitted... is there any chance i could be pregnant?
