Four days after starting pill ..

Ti

So had unprotected sex four days after I started the pill.. and just happened to be day two on dpo.. I just had my skyla removed and I was on an antibiotic.. a week later and my pee smells different and is really dark in the morning starting yesterday.. if I got a pregnancy test how soon could I test to be sure ? Not suppose to start my period for another nine days says glow but I am not sure since i had an iud.
