Small very itchy rash under belly button could be pups?

Hanah
I had pups with my first pregnancy it was horrible that's why I was induced (at 40 weeks)so about 2 weeks ago my belly really started itching just below my belly button and now have had a rash for a little over a week.. It's so so itchy and afraid it's pups. It's not as bad as my last pregnancy cuz its not all over my belly like last time. If it is God help me cuz its miserably itchy and NOTHING works except to deliver.
