Test question

Ally • TTC baby #1👶🏼💕✨

Hey guys so I just took a clearblue pink dye test. I have never only taken frist response and the clearblue blue due test not the clearblue pink dye test. Anyways after 3 minutes the control line was barely there, after a few minutes it did get darker but it took longer. Is that normal for this brand to do that or should I just retest again?
