Do I still take my prenatal vitamins?

Am

I found out today at 11 weeks and 1 day that I that I am measuring 7 weeks and 5 days but there is no heart beat. And they could not see the fetus in the sac. I am not a stupid person, I know what this means. I see my doctor Friday to discuss my options. But in the mean time is there any point in continuing to take my prenatal vitamins?
