Paraguard and pregnancy.. confused

ta

Hey guys, I just wanted to see if anyone has experienced this or if I should be worried (pregnant).

I’ve had my paraguard for 2 years now and i just finished my period, it was heavy as always and pretty normal. Since I’ve been done my period I’ve felt super bloated and I’m still having really bad cramps (not period cramps) in my back and in my lower stomach. I’m nervous to take a test but I will this week.
