Implantation

I woke up yesterday with some pink blood when I wiped. Figured it was AF because she’s suppose to start but used the bathroom again and it stopped. Woke up today and nothing except a tiny small pink dot. I have deep cramps like I would with AF and a pulling sensation in my stomach. My lower back also has a dull pain. The only other symptoms I’m experiencing is extremely emotional and slightly nauseous towards smells.

If my period is suppose to start now, I’m not even sure if this can possibly be implantation. My cycle is really messed up so I have no idea.
