To be honest, most of us have no idea?
Nothing was explicitly confirmed.

All we know is that, after their night stand, Euihyun went to the hospital to do a check-up. Now, whether or not he was able to confirm if the knotting was successful, only he knows.

He could be pregnant, I forgot if he took a morning pill or not.

i dont think that they know hes pregnant
