Should I take a test

Cat

So I just got my iud out (kylenna) about 1 week and 6 days ago, me and my bf had sex that day and have everyday since trying to convince, I’m been feeling off like my back aches my stomach hurts, I’ve been cramping or feeling dizzy or having to go number 2 a lot. I don’t know if I should take a pregnancy test. What do y’all think
