wondering if I should test? HELP 😭

I've been cramping ever since my period stopped almost a week and a half ago!! Tomorrow is my husband's birthday and I was thinking of testing today just to see! 
I know it's probably unlikely since I had a period but what do you all think? 
I'm also breaking out on my chin, the sides of my boobs are slightly tender, nausea at night, and the mood swings and fatigue... 🙄 
What do you guys think? I do have a doctors app in a week! HELP need advice 😭
