Loss of boob tenderness

So I’ve had slight boob discomfort the last few days. Today I have none. I’m worried. Is it normal for these things to come and go? I’m 4+4 today. Have my repeat betas tomorrow and I’m just worried that things are going to turn out bad again and I don’t think I can handle it.

Side note I’ve been testing every other day to see my progression and the lines have gotten darker.
