How urgent is potential icp?

I have an OB appt tomorrow, is that soon enough? My wrists started itching yesterday and I feel like im going to go mad from it now today 😫😫😫 I have such a busy day planned though because it’s my son’s birthday! 36w

*update - the call line nurse said localized itching is a complete non concern and told me to take zyrtec 🙄 I mentioned cholastasis and she said that would not be localized itching. So I sent my OB a message even though she’s off today and will see her tomorrow.
