Twins?!?!

I found out I was pregnant at 4w1d. I am now 5w6d, I took this test yesterday at 5w5d & I thought “woah! Those are some really dark lines!” Especially since my BFPs were vfl. Twins run in my family (my grandma & aunts have twins & one of my cousins had twins) but not in my husbands. Everyone’s tests that I have seen on here around 5-6 weeks weren’t nearly as dark. So now I’m wondering did anyone else have lines this dark this early & ended up having twins????
