13dpo and feeling hopeful. CD27 AF supposed to start 7/18

Even tho, l've been testing negative since 9DPO. I had peak LH test on 7/3 afternoon and we BD that day and the day after 7/4(also on 6/30 & 7/1) using preseed on all of those days.

Feeling hopeful due to the amount of symptoms I've been experiencing all last week (5/6dpo-now) I have a gut feeling this might be my cycle, but I've thought that other cycles and then AF showed

Anyone experience symptoms during the TWW and tested negative early dpo. But then got their BFP after 13dpo?
