Should I be worried about my TB test?

About 2 months ago I got a TB test and almost immediately the bump disappeared and there was not redness and the test came back negative. However, I got another TB test done about 6 or 7 hours ago and the area is red and has a slight bump. Should I be worried? I know that before they can read it that you have to wait 2 days, but it isn’t like the last TB test I took. Should I be worried that it will come back positive or am I just being paranoid cause the result of this TB test determines whether I get the job or not?
