Temps have plateaued?

Chantal

I know a few days ago I was very discouraged by the dip and then surprised when it went back up. This is my first month doing this so I don't really know what to look for. AF is due tomorrow or sat and I have been on and off cramping. I feel like the only possible symptom I have is ALL smells get to me 🤢. But then again, it could all be in my head 😂. So is this plateau normal or should it still be going up if I was pregnant?
