Should I be pissed at my fiance?

We were at Universal studios key adventure island and went on the wet rides. We were waiting in line and he was making a huge commotion saying I was having his baby and that I am pregnant and I shouldnt be going on this ride. I was embarrassed and said what are you talking about I am not pregnant. So after the ride was over, I was so pissed at him. He said i am overreacting? Am I? Thats embarrasing when I am not even pregnant
