Assuming not accurate ?

BBT shot up but I don’t know if it’s accurate or not because I woke up around 3 something and it was 97.70. I did change laying directions in my bed because my daughter was head butting me in her sleep. When I woke up near my normal time it was 98.49. I did take my temperature again about 10mins later in bed and it was 98.30 something. Is that accurate? I’ve also been getting more of the clumpy white sticky discharge
