Was this an immediate red flag from day 1?

So I missed a ton of red flags with this girl but we had a date later in the evening i admitted to liking her so we cuddled and watched a few of her favorite shows. Well it came time for bed and she went to her room she actually got upset because I slept on the couch. In my mind I thought that it was super inappropriate that I was sleeping in her bed with us dating for less then 24 hours even if it’s cuddling
