🤢Abdomen cramps and nausea...early pregnancy signs?

I believe I'm around 6 or 7 dpo right now but for the last couple days (always around noon) I get these terrible stomach aches and nausea. It goes away eventually but when it happens ohh it's unpleasant.

Possible pregnancy sign? Has this happened to anyone else before their BFP? My diet has been the same as it's always been so no changes there.

Any bit of help is appreciated! :)
