Iud strings lower

I am currently on my period and my iud strings are much lower. According to my dad's girlfriend, hers get lower during her period too, then go back up. Does this happen to anyone else, or has mine maybe moved down? I'm going to wait till after my period to worry, but. I can't really do anything if it has lowered, my dad is high risk for covid and I can't go to the doctor unless it's for sure a life or death situation.
