Hi, may I answer your health queries right now ? Please type your query here... hi i recently fell pregnant with the mirena iud coil in situ, i was around 3-4 weeks and misscarried, i bled for a week intermitently ten had my mirena coil removed. i obviously wasnt planning a pregnancy but after speaking with my husband we have decided to try, i had my mirena removed then had unprotected sex two days later, this was a week ago, since then ive felt exhausted with terrible thirst and queasy feeling, would it be possible to be pregnant again so soon!! with thanks. nicky.
