I was bitten by a spider maybe. Help me identify if it is Steatoda Nobilis or triangulosa

On Monday I found (Photo 1) and yesterday it evolved as seen on Photo 2.

Later I found two spiders, that I took photographs of.  They were 2cm and 1cm respectively.

I don't think I had a venomous reaction, because it already past 5 days since Monday, but it could be an allergic reaction or bacterial infection.

Can you help me identify if those are Steatoda Nobilis or Triangulosa?

According to the pictures, it looks like a False widow spider (Steatoda paykulliana) found here:

The only spiders that I have seen where we live now are the black widows. I have been observing them since 2013.

They seem really shy and will try to hide when I am around.

I have been bitten twice by what I thought was a spider though not a black widow.  Never saw a spider.  

Maybe knowing what your symptoms are may help identify what bite you.
