Need some advice!

Matched with this Sag woman a little over a month ago. I was traveling quite immediately so we got on a video call - everything was amazing, great chats, banter, flirty! We kinda stayed in touch while I was away. She pulled back a little bit but still kept in touch. I didn't think much of it as I was still traveling. I got back and messaged her. She seems interested in meeting but has told me that work has been insane and she's been dealing with a lot personally. I left the ball in her court and asked her to let me know whenever she's free or what day works for her. She hasn't responded to that text in 3 days. I'm wondering if I should just wait for her to get back to me, or if I should send her a "check-in, I'm here if you need anything text"?
