Is the Hook Effect actually a thing???

So on Saturday morning I got a positive First Response and than the same day at 3pm I got 3 more positives including a digital. That night my husband wanted me to take another test for him and it was also positive. I’m about 5 weeks and 2 days and I took a 2 more test and the digital was negative but the First response had a faint line.. is the hook effect actually a thing??? I suppose to be due December 2nd🤞
