Am I just overly paranoid?!

I'm 11 weeks 6 days today tomorrow I'll hit my 12 weeks, yay! 
However the last few days off and on I get cramps. They aren't by any means unbearable but they are definitely there and achy. I had a miscarriage a year ago on the 27th. I called the doc told them no bleeding or anything just cramps in my lower abdominal and back. They didn't seemed concern. So I'm trying not to be... I think I'm just freaking myself out. Anybody have cramps that are probably 4 or 5 out of a 10 pain level
