Implantation bleeding? Tmi..

I thought af had arrived this morning, isn't due till Thursday 20th

Only bright red pinkish blood when I wipe. A extremely light flow on the pad today and now nothing.

Been extremely nauseous for a week. Right side pain, back pain dizziness extreme fatigue. Is this just a extremely weird af or???

First month TTc

All rest up to this point 12dpo negative
