Switched temping methods mid cycle

Chelsea
So, my temps were really jumpy and all over the place, I sleep with my mouth open ( have since I was a kid ).... anyways, temps were all over the place, so I switched it up and started temping vaginally. They have been much more consistent since I switched methods, I'm just worried how much it could affect my chart? It's my first cycle temping, so I'm new to all this. Advice?
