I am 5 weeks pregnant masha Allah but I feel nausea only at times. Is it to worry about?

Some women are nauseous for the entire nine months !

So it is not necessary for every woman to feel nausea?

No, it is not necessary for every woman to feel sick.

Some women never are.
Some women are a little
Some women are the entire time.

There is no one case

Thank you so much :)
