Questions

Hi! I'm new to this and I had some questions. I just started trying to conceve a couple months ago with my 1st and I have not got my period yet, I was suppose to get it a week ago. I have had creamy cm for a couple days now and I have had sore breast for about a week to. I have not had nausea or bleeding though. Should I take a pregnancy test or just wait for af?? Sorry if this is a little confusing just ask me if you have a question and I wil explain :) thank you much for all the help
