iud help

Felecia • 23, mom to an adorable 1yr old

how do you know if your iud has shifted or is trying to grow into your uterus.....I had a very vivid dream about it and I've been having cramps on and off everyday for a little over a month now. they aren't pinful though just feel like. shooting pain or a twindge. I thought I could be pregnant but my test was negative. I'm still having symptoms though so I'm not sure what's happening and I don't have the money for my Drs visit right now.
