A couple questions?

Paris

AF came on the 10th and left the 14th. I threw up on the 14th was having hot flashes back aches etc so the 15th I was feeling better and ever since then I been nauseous everyday, got dizzy a couple times, etc so yesterday I woke up and went to the bathroom and saw a little blood after I wiped a couple hours later I went to the bathroom again wiped and there was blood only a little though so after that I haven’t seen anymore blood yesterday or today. I called the doctor she said with my symptoms I should take a test but it might not come back BFP cause I haven’t missed my period yet. Do you think I could be pregnant? I took a test but it was negative. Should I wait until it’s closer to my period to test again?
