UTI pregnancy test?

Kana

Can I get an accurate result if I am on uti medications when I take a pregnancy test? TMI** My urine is a dark orange color because of the UTI pills. I had sex each of the 5 days before I had my IUD removed on September 20th and also had sex that day and the 3 following days. I've only had the lightest spotting, and I am thinking in implantation bleeding, but maybe I'm just getting too excited?
