Test or wait?

My husband and I just use the pullout method as BC. Obviously not safe, but we're married and won't necessarily mind another baby.

My son is 9 months old and my period is now 2 days late. It's been pretty regular the past 5 months. I've been cramping pretty bad, emotional, my hips were hurting (an early sign I had with my son), and for dinner I made pizza, and as I dumped ranch on it, I had this overwhelming need for tomatoes and ranch (another sign I had with my son). TMI but I've been pretty constipated, but also feeling like I almost have diarrhea. Should I wait it out another few days or see if a test would read now?
