"i had my iud inserted on jan 21. almost a month later, i started to bleed as if it were my period. it was very heavy. my periods normally last 5 days and taper off almost completely by day 7. since february 15, i have been bleeding heavily. soaking through tampons and pantiliners with no end in sight. it&#039;s now march 3 and i&#039;m not sure how much longer i should let this go on before i see my doctor. they told me to expect bleeding but i&#039;m afraid this isn&#039;t exactly what they meant."
