Superstitious beliefs

Aslaamualaikum
If a muslim woman is quite superstitious. For example she believes/thinks if one woman falls pregnant then two more pregnant women will follow to make it a three.

This Muslim woman has a pregnant work colleague at her workplace. And the Muslim woman believes that pregnancies and similar things come in threes’. For example one woman is pregnant at work and two more pregnant women will follow at this workplace to make it a three . And this muslim woman also says verbally: ‘they(pregnancies) come in threes. So two more women will fall pregnant to make it three pregnancies. Its happened in my previous workplace.’

Does the Muslim woman become a kafir by verbally saying the above and having the superstitious belief as above?

Jazakallah
