Period is still late

Period is officially 3 days late, not really worried because im on new medications like victoza and blood pressure and i wasnt hungry for 3 weeks and was worried I am on BC i am sexually active pregnancy test at docs and home were negative so...lol doc took blood im just thinking its stress and my diabetes plus my anxiety and depression because I wasn't hungry and when i did eat i was nauseous and wouldn't eat for 2 days at a time because I felt like I was going to throw up plus id have to lay down and rest but i slept all day and my appetite was big today I felt like ive ate alot plus I've been craving milk and cheese and fresh fruits and veggies I normally don't eat tomatoes by themselves but they sounded and looked so good i ate all 4 so im not worried tbh I kinda wish I was pregnant but it'll happen 1 day.
