Wierd cycle symptoms

I'm supposed to o this week, I have ewm, like for real ewm for the first Time in6/9 months. But I'm cramping and having wierd emotional feelings like the day Af starts. I feel as if someone is putting sharp pressure on   The upper left side of my uterus. unlike Af when it's the center of my uterus. I wasn't tracking o  so idk if o earlier than I thought. So idk what's going on, I'm implanting at cd 16 or Af will start. I have no clue and just wanted to share my feelings.
