Should I or should I wait?

I just joined Glow a couple days ago and just realized that I was late when I had to enter my period for the last month. I am now five days late and not sure if I should go ahead and take the test. I don't want to jump into anything because since my boyfriend and I started trying (January), my periods were several days late and when I took the test it was all negative. So I don't want to freak out and get excited and then when it becomes negative again get disappointed. Anyway, as far as my period, it started being consisted again for the last three months. My boobs are extremely tender and I've been so emotional (I watched Pitch Perfect 2 the other day with my oldest and had to hold back tears just watching the previews!) Could this be it? Should I wait a week or so to be sure before I take the test? I need help!
