My body is going crazy!!

So I had my iud out about 2 months ago and after it was out I had the heaviest period I've ever had in my life then this month I've had random spotting twice and been nauseous and had cramps all throughout the month and the nausea and spotting keeps getting my hopes up for a pregnancy it's driving me crazy and it's really wearing me down physically the cramps are bad have any of you ladies experienced anything like this after stopping birth control or have any idea what could be going on HElP 😢😔😰
