Swimming in circles

Just went in for my first ever <a href="https://glowing.com/glow-fertility-program">IUI</a>. They said that half my hub's swimmers were not moving at all and the other half are swimming in circles. The stand-in doctor for that day said very little except she would recommend <a href="https://glowing.com/glow-fertility-program">IUI</a> tomorrow. Anyone have the same experience? What's the likelihood of getting pregnant? If I do get pregnant will baby be ok?
