For example, if she sees in one month on the 15th, the next month on the 16th, the next month on the 17th, and the last month on the 18th according to everyone she establishes a veset that she'll continue to see on consecutive days of the month.

The Ran Shevuot 4b-5a s.v. garsinan understood Rashi that there's an Onah Beynonit even if a woman has a fixed veset but argues that the concern of Onah Beynonit should only exist if she doesn't have a fixed veset.

Igrot Moshe YD 1:122 isn't certain that we follow the Chavot Daat where the veset of the day of the week is consistent but is sure that we follow a haflagah if the day of the week is increasing.</ref>

	#A woman who doesn't have a fixed veset (established with 3 times), which is very common, has to observe a veset on the 30th day from her last period and that is called an Onah Beynonit.<ref>*Rashi Niddah 15a s.v. Bitoch explains that a woman is concerned about a 30 day veset since by default that's when a woman sees her period. The Ramban (Chiddushim 15a s.v. vehu) supports this opinion from the Yerushalmi Niddah 2:4. The Rashba ([http://www.hebrewbooks.org/pdfpager.aspx?req=8922&st=&pgnum=367 Torat Habayit 15a]) based on Rashi writes that any woman who doesn't have a fixed veset needs to be concerned about the Onah Beynonit. The Ran Shevuot 4b-5a s.v. garsinan understood Rashi that there's an Onah Beynonit even if a woman has a fixed veset but argues that the concern of Onah Beynonit should only exist if she doesn't have a fixed veset. The idea of an Onah Beynonit is codified by the Tur and Shulchan Aruch 189:1.		#A woman who doesn't have a fixed veset (established with 3 times), which is very common, has to observe a veset on the 30th day from her last period and that is called an Onah Beynonit.<ref>*Rashi Niddah 15a s.v.
