On the 41st anniversary of Roe v. Wade, in 2014, she arranged for a sonogram to take place in the Kansas Statehouse during a meeting of the Senate Public Health and Welfare Committee. The ultrasound procedure was performed on two women by Cindy Patterson, a sonographer with Wyandotte Pregnancy Clinic, a crisis pregnancy center that pro-life counseling to women considering abortion.
In January 2014, she introduced Senate Bill 302, which would have made surrogate motherhood a misdemeanor. Under the bill, anyone involved in hiring, or working as, a surrogate could be charged with a misdemeanor, punishable with up to a $10,000 fine and a year in the county jail. The law eventually died in committee.
In 2014, Pilcher-Cook introduced passage of sex education bill after one of her a parent objected to a poster which was placed in a middle school health classroom listing several sex acts.

In 2011 and 2012, Pilcher-Cook worked towards passage of the Kansas Health Care Freedom Amendment, which would have amended the Kansas Constitution, which failed by one vote due to resistance by the Republican leadership. However, a bill simply placing the same language in statute, called the "Kansas Health Care Freedom Act", was later adopted and was signed into law by Governor Sam Brownback.
