Chart Question

Amanda • I`m 24 literally married my best friend of almost 10 years May 9th 2015. He has 2 boys 6 and 2 we have been TTC our first baby since March2015. I thought this would be easy as pie, ha I sure was wrong
This is my first month testing daily, I feel silly for asking but how do I get the control line? All these charts I look at have a red line and the temp stays above it. Mine doesn't have a line
