On the 11th of this month i got the iud for 10yrs for the first time and since than I've been bleeding at first it was just spotting and since monday I've been bleeding like a period. My periods are usually heavy since day 1. I wear the night pads for that reason their suppose to last 10hrs but only lasting about 4-5hr and at times even 3hrs. Should i be worried? Should i make an appointment with my ob?
