Cervical fluid impedance measurements throughout cycle. A Cervical fluid impedance measure of follicular, ovulatory (single day of ovulation), and luteal phases. Bars expressed as average and standard deviation. Statistical differences were found for the impedance measurement of the follicular phase versus ovulatory phase (p = 0.007) and the impedance measurement of the luteal phase versus the ovulatory phase (p = 0.007). When focused on individual days, significant differences were found in cervical fluid impedance between days − 7 and day − 3 (p = 0.0138) with trends in lower values as you approach the ovulation day. C Basal Body Temperature (BBT) measure of follicular, ovulatory, and luteal phases. Bars expressed as average and standard deviation. Statistical differences were not found for the BBT measurements of the follicular phase versus ovulatory phase (p > 0.9999) and the BBT measurements of the luteal phase versus the ovulatory phase (p = 0.4463). When focused on individual days, significant differences were found between − 2 and 11 (p = 0.0091) and − 1 and 11 (p = 0.0079). Significance was assessed at *p < 0.05, (**p < 0.01)
