WHEN TO TEST??

I'm due for AF in 4 days...now usually my breast would start hurting 1-2 weeks prior but here it is 4 days before and their fine. I noticed today that for the past 2-3 days I've been feeling nauseous and super hungry when I wake up in the morning. Now about a week ago I did feel a light cramping but didn't really think nothing of it. Now that I have some free time I've sat back and put all this together and now I'm wondering should I test now or wait to see if AT comes? This is our second month TTC and I'm freshly off of birth control (Pargard IUD).
