Negative Test 9DPO

I know it’s still early but it’s a bit discouraging. Has anyone else had a negative test at 9DPO and gotten a positive later on? My boobs have been SO painful! I had to go buy a more comfortable bra because I couldn’t stand to wear the bras I had. So sore that it woke me up one night. I’ve also had very vivid dreams and I’m remembering them, which never happens. I almost never dream. Other than that I’ve really had no other symptoms that stand out. Thought for sure the dreams were a sign.
