I am also B+ blood group.
My DNA is 68.2% English, 22.2% Irish/Scottish/Welsh, 4.4% Scandinavian, 3.8% Ashkenazi Jewish, 1.4% North Africa.
I have known Irish Ancestry.
I would love to know where the Ashkenazi Jewish comes from.
It's looks as if you've tested with MyHeritage. So have I. I tested earlier with FTDNA FamilyFinder, and they sent me one set of results - e.g. 0% Scandinavian, 32% Western & Central Europe - then they emailed me revised results, e.g. 33% Scandinavian, 0% Western & Central Europe. I've had 5% Finland and North Siberia, which later disappeared, and I got a small percentage of Sephardic Jewish. That has disappeared with MyHeritage results, but they gave me back a bit of Finland and the Baltics (thanks for that!), and 1% each of Nigerian and North African. Truly, you pays your money and you takes your pick.
I can remember, in the days before genetic genealogy, when you could get car stickers in Scotland saying Pict, or Scot (can't remember if they did an Angle one). The point is, you could decide what you were, whatever appealed to you most. In the same way, I think you can pick your favourite ethnicity out of your autosomal DNA test results and stick with it.
