Dark line... twins?

Rachel

So I heard a weird myth that if you get a very dark line early (I’m 5w4d) that it could mean twins.

Since my first test they have all been pretty dark.

This test was 6pm after a day of drinking water (a lot of it) all day at work... thoughts?

I’d be happy either way but just curious. US is tomorrow at 1pm so I’ll find out then 🤞🏻
