Generally yes; I believe this is fairly well studied although I'm short on sources. IIRC, during ovulation, a woman would dress up with brighter colors (or dress nicer or something), have more flirtatious actions... I forgot if there were dietary changes. Also interesting (also IIRC), is that women prefer more masculine males during peak fertility (best genes), and prefer more feminine males during lowest fertility (best care).
