Still hoping there's a chance.

So at 5dpo-7dpo (which I know is still early) I was experiences the worst nausea, headaches and lower back aches I think I have ever experienced..  Today at 8dpo it seems to mildize a lot more, but I occasionally feel queasy and a headache comes and goes but not as severe 5-7dpo. I recently got over the stomach bug two weeks ago, and it was completely different than this.. Anyone else experience this? Or even wishful thinking ended up with a BFP? Any insight wouldn't be lovely 😚
