I'm 9dpo and I have had a terrible headache since Thursday and it's been holding steady this afternoon. I've also been cramping pretty badly these last couple of days, and when I took off my bra to get in the shower, my boobs felt heavy and slightly dull-achy.
Of course, it could all be in my head or a sign from AF, but at least it's something. Don't want to get my hopes up, but dang it, these cramps are sharp!
Still too soon to POS.
