DPO 9 could this be early pregnancy symptoms?

Sarah

Have been nauseous everyday off and on for about a week. Been getting cramps and flutters in my belly and back pain for a few days. These come and go and at times feel like period symptoms. AF is not due until next weekend. I have never gotten pms symptoms that far ahead of when my cycle is due to start. Tummy feels tight. Do have some heartburn going on every once in a while. Took a test this morning and it was negative. Could this be early signs that it just might be my turn???? Or maybe I’m just that much of a mess this month lol?
