B’sha’ah tovah!
There is a difference of opinion regarding whether a woman is released from bedikot for vesatot as soon as she has a positive pregnancy test, or only once ninety days have passed from conception. In practice, if there is no bleeding, the only practical difference is the first set of vesatot, since after they pass there will generally be no vesatot to observe in any case.
We follow the view that a woman should perform this first set of bedikot on the haflagah, chodesh, and onah beinonit. If there are extenuating circumstances that make this especially difficult, then the more lenient view can be relied on.
Please do note that a woman can become niddah from uterine bleeding even while pregnant.  To review the precautions against becoming niddah unnecessarily, we recommend reading our articles “Stains” and “Toilet Paper.”
Please let us know if we can be of further assistance.
