Should I ask her out? (Long read)

I recently came out as bi over the summer. One of my best friends did too. Anyways...I have a crush on her, I’ll call her S. I made a yolo for my Snapchat asking “would you date me” I got a few yes and the day after at school she came to me and said she was the one who said yes. About a week after that S made one saying “me and who would make a cute couple” of course, I slid up and said my own name. She replied with “😉.” After another few days she posted the exact same thing I replied with my name again and she said that she wouldn’t be against it. Should I take the chance and ask her out or should I wait. If so I need suggestions on what to say... thanks!
