My body playing tricks on me!!

Period is due tomorrow. Last period was 8/20-8/25. Ovulated 9/3

-7dpo breast are sore,feeling nauseated, very bloated,

-10dpo above goes away and vvvfl on frer

-12dpo negative frer and nothing else

-13 dpo today cramping earlier today thought the witch was coming but cramps were gone in a hour no spotting or bleeding and now my nipples are tingly and stinging and my areola looks swollen like when you breastfeed and are engorged.

Is it possible to implant at 13dpo with irregular cycles? My cycle varies between 28 and 32 days
