Rise in BBT

danielle

My bbt is high this month for the past 7 days. Normally it will range between 96.55-97.30. The highest it got the last month was 97.5 But this month they are all over 98.10. Is this an early sign of pregnancy? I have also had sticky CM the past 2 days. The first chart is my bbt now. The second chart was last month so you can see the difference.
