7dpo and spotting

Hey, I’m 7 dpo and been having light cramping the past couple days. Today when I wiped I had the lightest pink spotting could bearly see it. Been having lots of discharge. I dont know if that’s relevant to any of this lol.Period suppose to start in a week.I confirmed ovulation also and I did the sperm meets egg method. I never had this happen before. So confused on what’s going on. Any opinions on what you think it could be ? Has this happened to anyone.
