I'm currently 13 DPO and had unprotected sex the last 3 days of my window (pulled out all 3 times).

Lately I've had things that are weird for me:

-super tender breasts (very unusual for me for PMS)

-weird cramping above belly button area in stomach

-smells are super strong and overwhelming sometimes

-exhausted even when I get enough sleep

-had light pink CM Friday which usually means AF later that day, nothing happened. Normal white CM all weekend.

-AF supposed to arrive yesterday and didn't

Took a test yesterday night but was BFN.

Is it possible I'm just too early to tell or am I stressing for nothing?
