Question:
If a women did a bedika on the night of her vest and saw some blood on the bedika cloth but her real flow didn’t start until the day- when is it considered that she “got her period”?
Answer:
Since your period was close to the time of the bedika, then the veses will be from the time of the bedika, and we will say that it started then, and she will make her bedikos as if she saw at night.
