Am I pregnant

This is the first time me and my boyfriend have tried to get pregnant we've had sex when I was ovulating on the best day/highest percentage to get pregnant on.. we conceived on February 3th i've had some mild cramps and a lot of diarrhea I know tmi but oh well .. my period is in a week and I believe I have started spotting.. I have blood down there but not enough to fill up a pad or tampon if I am spotting it's the second day it is super light but the main concern I'm having is could this be a sign of early pregnancy I already know you're supposed to wait till after your missed period to take a test but what do you do when you have wanted this for so long girlsss I need help/advice
