I bought a slendertone belt about 1 year ago... I used it for 2 or 3 days and then I started cramping real bad and bleeding vaginally. It wasn t a period kind of bleed...lasted several days but no clots or anything. I thought i might have been pregnant and it caused a miscarriage , never confirmed. It scared me so I didn t use it again until a few days ago ...one time...and by morning I was bleeding again. I have googled this and can t find anything that helps.
