Conversation pretty much dead after first date! please help me

I went on a date with this girl last week, and it was genuinely one of the best dates I’ve ever been on! We had a lot of fun and we laughed a ton! And we even had a good conversation over text the night of the date! But ever since then she’s been really dry and has been taking a lot longer to respond... I’d love to go on a second date, but I can’t really gauge where she stands? And I’d prefer to have a good conversation that can lead into asking her out, so if anyone has any advice on what I can do to help pick the conversation up I’d really appreciate it.
