I don’t know if I’m pregnant

So I had my last period on September 12th. Then September 27th to the 29th, I had slight bleeding. I haven’t gotten my period up to this day since but have been experiencing nausea, fatigue, back pain, sore breasts, and today I actually regurgitated. All my tests kept coming back negative last week but I haven’t taken a test this week. I have an appointment on the 15th but it kills me not knowing. Is there any way you can get a false hpg but positive blood test at the doctors?
