Start of a line? Look closely :)

I had a massive bbt dip two days ago and it shot back up the next day and has remained high. Today is two days after the dip, so I thought why not? Pic within time frame. I’m planning on testing again this evening, and again in the morning. I’ve never gotten an evap or indent on these, so I’m hoping it’s there! I appreciate you looking :)
