Anyone have AF symptoms on 12 DPO but then wind up being pregnant?

Has anyone had what they thought were AF symptoms on/around 12 DPO and figured they were out but then didn’t get AF and wound up pregnant?

If so, what were your symptoms? Was it exactly like your normal AF symptoms?

I’ve gotten all BFNs after my initial vvvfl FRER on Saturday so I guess I’m grasping at straws here but... maybe there’s still a chance? Maybe I implanted late and my cramps are from implantation?

I’m also super tired, super cranky, and a little nauseated with a bit of heartburn.

Help. 🥺💔
