Could i be pregnant or just stressed out?

i usually get my period between 23-25 days and i am now on 30 days without a period. my bf and i have been trying so it would not be a bad thing if i was but at the same time i am very stressed due to a possible new job and moving and family issues so im not sure if that is it. i have noticed some symptoms that coincide with pregnancy such as food craving especially for mac & cheese and honey roasted peanuts, i have suddenly stopped wanting eggs for breakfast in the morning, i get waves of nausea, im very tired, feeling out of it and headaches. any help would be great. this would be my first baby.
