Symptoms that led to BFP...

Im just curious what made everyone test, what symptoms yall got/have? Alittle on my story hubby and I stppped ttc not to long ago just wanted to enjoy each other, on may 30th I was in a bad car accident and have since had horrible pain on my right ovary. On sunday June 21st I went to the hospital had ultrasound and pregnancy test show nothing then on the 24th I went to the doc as a follow up she took blood for what she thought was an apendix problem and just wanted to check my hcg before sending me in for a cat scan. Got a call the next day and bam she tells me your pregnant, I am over joyed. Now just waiting on the hubby who is slowly getting excited.
