I asked my female colleague to hang out and she hasn't responded for 3 days, should I text her again?

I have known her for quite some time and we have gone out a few times for dinner and a walk (just us). Just the last time we gone out, I sneaked a little toy into her bag thinking it would surprise her when she got home, but in the end she told me that she couldn't find it (maybe it was lost somehow). She also told me I should ask her for days she doesn't have to work so that she is not so tired.

So I asked her to hang out at a new restaurant with something to play and asked when she is free. She hasn't responded and it has been 3 days. In the past she ALWAYS respond to my text. Should I send her another text? if so what should I say.
