Sample Basal Body Temperature Chart I Started Charting My Basal Body Temperature...?

I started charting my basal body temperature...? - sample basal body temperature chart

Hello I started my basal temperature mapping for the first time a few days (4 days to be exact). I have the problem is that during the last 4 days, my temperature is almost equal. (1-97.07 daily 2-97.17 days 3-97.2 days 4-97.16).

Take your temperature at around 7:30 ET, in my minutes or less, but not much. Is this normal or am I doing wrong? Miro graphics of the sample and it seems that the temperature should be as close. Has anyone else experienced? What am I doing wrong?
I slept for part-time, I tend to wake several times during the nite. But do not try to go to the toilet for at least 3 hours before taking my temperature.

I am of the 8th Day of my cycle I (I do not, the first 4 days of my period) and the second cycle of BCP so I do not know if that has something to do with it.

please please help me thank you
