What do you think?

I think I am 7dpo or around that and I woke up with nose congestion yesterday morning and a slight sore throat barely noticeable. Me and my fiance went and got 2 pregnancy tests today but I haven't took one yet. Now its 4:11am and I still cant sleep because I have a headache and a runny nose. I been having diareha all week and minor minor cramps that only last a minute also I stay hungry and I just felt a little off lately I kinda feel like I have buterflys in my stomach. I was wondering can I take one of the pregnancy tests in the morning in hopes of a + or do you think its so soon?
