Fever/chills

Molly • Pregnant with baby number 3, with my husband, who I've been with for 6 years. We have 2 sons ages 4 and 2. We're so excited to be welcoming another baby! Due late september!
37w 4d and I've had a fever on and off all day and chills. Would this warrant a call to my midwife? I have an appointment with her first thing in the morning.
