im healthy in every way, no medical problems. im 22 years old. i had the mirena inserted 7 months ago and have not had any bleeding for the last three months. for the past 2 days ive had horrible cramps and today started brown spotting. again, no bleeding at all for the last three months. the cramps are almost crippling and ibiprofin is like candy for the pain when usually it will help me with anything. VERY dizzy, nauseas, and always tired even if i get 20 hours of sleep. pregnancy? mirena complications? thanks
