Five cultural beliefs associated with pregnancy/prenatal development

Use at least 3 valid research method (books, professional periodical, oral interview, website or other reliable source) to identify 5 cultural beliefs associated with pregnancy/ prenatal development. Associate the culture with the belief and specify the research method and source for obtaining the information. A maximum of 2 beliefs per research method may to be used.

Reflect upon and create a written response explaining how and why these beliefs influence the lifestyle of todays pregnant couples.
Also, I need a work cited paper.
Thank you
