Dpo 6 symptoms

Hi all! I’m trying to just go with the flow here but easier said than done! I’m either dpo 6 or 7 (I had strong lines on an opk for 2 1/2 days so I ovulated some where in there). I had some strong left side cramping yesterday and very light cramping today. Is this implantation or AF coming? Other symptoms:

Dpo 3- nauseous, headache all day, sore boobs

Dpo 4 til today-no sore boobs, just camping

Today (dpo 6)- creamy cm (sorry tmi for the pic), light cramping

Help! Anyone else have these symptoms so soon? What do you guys think?
