What do you think?

So me and my hubby have been TTC for over a year now and these past 2 and a half weeks we've tried every day and I haven't taken a test because my af isn't due till 3/27 but the past couple days I've been really moody and super sensitive my hubby said he has noticed a big change in my attitude some days I'm fine then a couple hours later I'm a crazy person I've also been experiencing sore breast and back pain then yesterday morning I started puking my guts up and have been ever since. my appetite has changed dramatically also im always eating something.. I'm not really sure what to think could this be signs of being pregnant or just a really bad week...
