When you lose bloodline points, for example due to failing to respond to a random event, do you also lose blood abilites?

For example, I started with a Bloodline Strenght of 9, and no Blood Abilites. During the game, I reached Bloodline Strength 11, and I got a Minor Ability. Then, due to a failed event, I went back to 10. Do I lose my Minor Ability?

thanks in advance
