Abdominal Pain day after IUI??Normal??

As

I had my <a href="https://glowing.com/glow-fertility-program">IUI</a> yesterday at 7:30am no pain or cramping during or after for the whole day. I woke up middle of the night and also this morning with an ongoing feeling of fullness and “air” in my lower abdomen. It’s not gas pain and it quite cramping.

Is this normal? What is this? I have had 5 previous <a href="https://glowing.com/glow-fertility-program">IUI</a> and haven’t had this yet.
