Can I be pregnant?

Ok y’all... So please don’t judge me..

I’m a ftm. So I’m on the iud.. I’ve been on it since last year in November. And Idk what the heck is going on with my body! Ill spot and then the next day I won’t have it and the spot and then won’t have it, etc. I’ve been craving junk food, nauseous, headache, so tired, and bloated. The tiredness and craving junk food started 2 weeks ago and everything else was last week for a few days. And Today I just feel so bloated!

I took a pregnancy test this past weekend(September 14) and it was negative. Should I take another one?
