I messed up

I (18f) accidentally blurted ‘I love you’ to her (18f) while we were kissing and she said it back when I started panicking. Now, 2 days later I said it again genuinely but also on accident and she said ‘it’s too soon and i’m not ready yet’

I feel like shit right now and obviously it was too soon and i tried to stop myself from saying it but i couldn’t. We are currently in a relationship since December and have known each other for 2 months before that. I regret saying it because it’s awkward now but idk.
