worth testing?

my period is due in a couple days (3), i have the skyla iud (still have 10 months until it expires)

but ive been feeling off lately, either always tired, or wide awake at night. during the day (i’m a nanny) i don’t want to do much but hang out at the house. I’ve been bloated a lot (which isn’t too normal) and i’ve been getting cramps a lot, usually a week before i’ll get small cramps achey but not crippling and nothing else. these cramps are sharp pains, on my right side, in the middle, and they don’t go away right away. i’ve also been a little nauseous after i eat and always hungry. i know most of these could be pms but they are different then my usual pms.

would it be worth taking a pregnancy test?
