Frequent Urination

Wednesday my boyfriend and I had sex, he was pretty big) we didn’t use a condom although I am on birth control. We had sex again on Thursday. Now 2 days later, I find myself going to the bathroom every 15-30 mins. When I do pee, it only last like a few seconds, not like I normally pee. There’s no discomfort when I pee. And the color is either a light yellow color or clear. Could this be a UTI?
