I might be pregnant

Okay so, my period is like a week late . I have a doctors appointment today but I’m really nervous . Last time my period was this late I was pregnant . I wasn’t on birth control back then . Now I am, I have the copper IUD . Had for 3 years now . So is it possible ? I get cramps & stuff but no spotting. I have a lot of cravings I get nauseous I am always sleepy & hungry . Exactly how I felt almost 4 years ago when I got pregnant .

I just need opinions, thoughts, experiences.
