Am I pregnant?

I am 9 days late and don’t know what to do. I took a pregnancy test 2 days ago and it came out negative but I think I took it wrong because it was one of those before your missed period ones. I do have irregular period but not like this. I’ve noticed I have been wanting to eat more but I also have been getting high. I don’t feel nauseous but I sometimes get cramps and my boobs hurt normally. Maybe it’s my period coming? I haven’t had sex in 2 weeks but im still very anxious. What else can it be
