no period

Alexia
Hey guys! I have PCOS and have been TTC for 4 years now. The past 6 months I have had regular periods. My first day of my last was May 27th. I should of already started but haven't. I've been more tired lately, pinching/cramping, a little nauseated, and it feels weird to lay on my stomach down by my uterus. I started to lay down today and it also feels heavy. I don't know if I should test or what. Before now I have never gotten any of the symptoms and I'm not sure. Any suggestions?
