Out this month?

Thought my chart was looking great and possibly even triphasic then got a huge dip today which happens the day before AF 😭. Keep holding on to a tiny piece of Hope because I think I actually O’d on the 5th so today would be 10 DPO- so this could be an implantation dip? I’ve had weird dizzy spells and super sore breasts so I really thought this could be the month.
