Is this line too dark?

I've heard that if your line is really dark it could be an indication that you're having multiples, which is terrifying to me lol. This test was done at 4 weeks, 1 day, around 3pm so not FMU. I'm sure I sound crazy but I don't have a Drs appointment until the 22nd. What do you all think?
