It was narrated from 'Aishah that Umm Habibah bint Jahsh who was married to 'Abdur-Rahman bin 'Awf suffered from Istihadah (non-mentrual vaginal bleeding) and did not become pure. Her situation was mentioned to the Messenger of Allah (ﷺ) and he said:
'That is not menstruation, rather it is a kick in the womb, so let
her work out the length of the menses that she used to have, and stop
praying (for that period of tie), then after that period of time),

The above hadith has answered your question. Here, "A kick in the womb", in other narrations means "A kick from Shaitan," meaning that the Shaitan uses it to confuse her about her religious commitment.
The devil (satan) is always vigilant and never ceases attempts to mislead us from the straight path.
Our beloved Prophet (PBUH) said in an authentic hadith that,
I heard Allah's Apostle (ﷺ) as saying: "The Satan is present with any

The devil has full control over human's heart. Whenever we remember Allah, the satan withdraws. And this is how Satan deceives us in thousands of ways.
Since Allah has given Muhammad(PBUH) such information about Satan and that's why he(PUBH) has uttered the above phrase which is "A kick in the womb" meaning that the Shaitan uses it(Istihadah) to confuse her about her religious commitment.
And Wallahu 'alam
