I think it fell

🦋B

So i got my iud about a week and half ago..the bleeding stopped after 4-5 days...i had no cramping..i was at work i had to go to the bathroom..when i went i thought i say my iud in the toliet (but it was a quick glance while i was flushing the toliet) i wasn't for sure i was going to wait it out until my next appointment..but now she has this weird smell, little spotting, horrible cramps,and back pain. Has this every happen to anyone?
