Me and my boyfriend had sex everyday while my fertile window was open, 6 days. Now 12 days later I'm having frequent urination and spotting...not sure if a UTI or not...

We had sex on the 22nd & 23rd , during the day on the 23rd i had frequent urination..and yesterday the spotting started. Im freaking out honestly...i couple months ago i had serious baby fever, really wanted to have a baby , but today i get my keys to my first apartment and i am definitely not trying to hear the news that im pregnant
