Confused about temping

Chelsea
This is my first month tracking my temperature. I have a regular vicks thermometer and not a special basal one. It's pretty consistent at 36.5.One day at 36.4 and one day at 36.7 on day ten. I am on day 17 and coming up to my "most
Important days". Will I see a temperature spike with that thermometer ? I know I need to be patient lol
