Really upset w/ SO

Samantha ā€¢ I have an amazing husband we have been together 7 years we have a beautiful little girl who will be 5 in April! We have been ttc since November 2014. I'm a dog groomer šŸ˜‡šŸ˜‰šŸ˜šŸ‘ŖšŸ’–
He turned the heater up a few degrees this morning. I just took my BBT and it's reading at 98.8. -.- so now I don't know what I should do. Should I record it or skip today and do it tomorrow morning?
