People with vvfl BFPs help me!!

CB15

Hello all, today is 9dpo and i got a vvfl in frer today morning. I had bad nausea last night. Now after i saw vvfl,as the day progressed i feel very normal. I dont see any symptoms or anything. I saw vcvfl exactly at 3min(i timed the test) so it cant be evap line. But now i am worried. Do people with vvfl bfps have symptoms or some “feeling” all day? or is it just now and then? please help!
