Lost IUD

Relly

So I went to the Er due to my period being so heavy and painful and I told them I also have an iud but I couldn’t fill my stings anymore and could they check it for me ..so they did a ultrasound and then said they didn’t detect an iud at all ..and I’m like wtf what do you mean I just got it may 2019 and it’s only January and its not there ..could I now get pregnant?
