I agree with Shannon. I freak out all the time about this sort of thing and my mom has told me time and time again that it takes awhile for the symptoms to show. Don't worry about the weight gain, that wouldn't be from pregnancy at this point. Your late period on the other hand may be something to keep an eye on, but don't worry just yet. Is your period usually irregular? If not it's probably something to do with the factors you listed above. I wouldn't worry about it too much right now. you're probably fine, but if you don't get your period within a couple weeks then definitely take a test. Best of luck
