I feel dumb for asking but...

I had unprotected sex about 2 weeks about but he didn't cum in me all the way if that makes since. I'm not supposed to start my period until Friday 
 But ever since then I have been having horrible mood swings. I've been eating everything I can even stuff I normally don't like. And I have had to pee all the time. And I have a phobia of peeing in public bathrooms but lately I haven't been able to hold it in. 
​Please don't be rude I'm just asking.. 
​Is it to soon to test? Should I wait and see if I start? Are these possibly symptoms of pregnancy? Help!
