Test now or test later?

According to the pattern my periods have been on, I should've seen AF today. However my cycles have been short since my IUD came out at the end of January so I don't know if my cycle is trying to go back to a regular length now. I'm thinking that could possibly be the case since my CM was eggwhite later than usual, which would make AF due by the 29th or 30th.

On the flip side, my boobs are sore, I've been nauseous a couple days now, and when I was doing laundry a bit ago I was getting dizzy. I know tests can usually show positive a few days before AF is due anyway. Should I test now or wait it out?
