BBT Chart Help!

Ceci • South Florida
This is my first month charting my BBT.  This is what I have so far.  Does it look right?  How long does your temperature stay up after ovulating?  I can't seem to get the whole chart in one picture, but before ovulating my BBT was between 97.4 - 97.7...never higher than that until after ovulation.  Any input is appreciated, as I've never done this before.  Thanks!!
