Questions for twins!

I have twins on my mind because they run in my family. I know I know that the darker line on a pregnancy test doesn't always mean twins but anyone with twins did that happen? I got a huge fat positive at 9 dpo. By the day of my missed period the line was many shades darker than the control line. About 4 weeks 5 days I look an internet cheapie because i was paranoid but the line was almost black than purple LOL and the other line was faded. I keep seeing other peoples tests and someone just posted at 5 weeks the line on a cheapie is finally the same color 🙄 mine was the same color by like 12dpo lol (first response, then day of missed period internet cheapie)

But maybe I ovulated earlier. Just seems like I have a high amount of HCG lol

Curious people! What are your experiences?🙈
