Actually, a raised temperature is more indicative of implantation. From Mayo Clinic: Raised basal body temperature. Your basal body temperature is your oral temperature when you first wake up in the morning. This temperature increases slightly soon after ovulation and remains at that level until your next period. If you've been charting your basal body temperature to determine when you ovulate, its continued elevation for more than two weeks may mean that you're pregnant.
