What Causes Frequent Urination After Having Intercourse For The First Time?

I'm a 26 female and had sex for the first time about 5 days ago. The past 2-3 days i have had to pee a lot and my bowels are not normal and more frequent. The first two days I bled a little but that is gone now. Is this a normal sympton after having sex for the first time. I thought that their can't be signs of pregnancy this early.
