Soooo confused.....😭

I know they say not to test after your first positive...but I did 🙈 and now I'm confused....I thought I got a positive OPk on CD 17, it went lighter CD18 but it's seems super positive now on CD19!!!! Shouldn't it be lighter by now..... Please don't bash me I know I've made a mistake in testing again...🙈

6th test- CD17 7th test-CD18 and the last one is today at CD19. My problem is because I placed it in glow it's now lush by ovulation date back when really I should be 2DPO by now.... Xx
