Help am I pregnant or no

Valerie

Okay so I’m 14 dpo and I’ve had sore boobs near my armpits and nauseous and light back pain also my CM is white and creamy and I’ve been beyond sleepy. I took a cheap test at 12 days and it was negative. So I’m taking a FRER test in the morning I’ll be 15 dpo so if it’s negative as I out this month?
