So confused 😕

I really thought I was pregnant but I got a negative test this morning. I'm three days late (16 dpo) and no sign of AF in sight. My cervix is med/high closed and soft, I have been feeling exhausted, tender breasts, and was nauseous/throwing up yesterday.. I have also had light cramping for 4 days now which isn't normal for me.. Guess I just wait some more to see if AF shows.
