BBT temp help!

Lindsay • Due July 20, 2015 with our first. ❤️
This is my first month tempting. I have read its important to take your temp first thing in the am before you get up, but also that its important to take it at the same time every day. Usually I set my alarm for 7am but sometimes have to get up in the night to pee. I took my temp at 4am today before I got up and it was 96.82, at 7am it was 97.45 which is very similar to yesterdays temp. Long story short - is it more inportant to take it before you get up or at the same time in the am to see a temp flux? Only CD 10 so not expecing ovulation yet. I just want to be recording accurately to help spot it.
