Tweak my test

Rachel • I'm 35years old. Happily married military wife. Have been trying to get pregnant for about 3.5 years and have now been confirmed pregnant by blood test. Due Feb 2020
Can someone tweak my test?? My bbt is usually like 97.2-97.7 at most in the morning. March 4th it was 97.9 and then March 5th it went up to 98.2 and has stayed up for the past 10 days being over 98.4 the last 5 days in the morning. My temperature had never been raised over 97.7 in the mornings.
