All day sickness

According to the app I am 11 weeks. I haven't had my first appointment yet, thats tomorrow! 😬 I have dealt with sickness/tiredness all day since day one. I still have the tiredness all day long, but my nausea has started to fade woo woo. If I don't eat as soon as I get up I will start to feel sick. When I brush my teeth I gag the whole time but other than that, no more sickness! Does this mean that my app due date is close? According to that I should be almost through my first trimester. Obviously, I know tomorrow I will find out for sure...but i just wanted to see what you all thought.
