In need of conversation advice

Hey guys I was wondering if I'm overthinking this conversation. So I (M22) matched with this girl (F21) on bumble last Monday and this was the first match that I've actually had a good conversation with. We talked Monday and decided to talk again on Wednesday which led to us talking all the way to Thursday morning. But due to finals I didn't get a chance to text her until the next Monday. But unlike before she hasn't responded. Should I be worried? Or am I overthinking this cause I don't get to many good matches.
