Here is my chart, think possibility of implantation on 8dpo. Had some sharp pain on the right side in my lower abdomen yesterday afternoon for a few hours. Though maybe af was coming but not due for a full week yet ?

Also been feeling SUPER TIRED ! irritable just generally off and feel sick. Had a slight hotness to my body yesterday felt tad feverish but no high temp ? No motivation for anything just want to lye down and sleep 😥...

Never had a dip in any of my previous cycles like this so I am kinds hoping this cycle is it.

Anyone had similar chart and symptoms, had BFP ?
