PUPPS bloodwork?

So about 2 months ago I started getting this light under boob rash. Few weeks and it went away. Ended up coming back worse on the upper chest area and continued to the center of my chest. Doc gave me a yeast cream to try for a few days and nothing. Then she gave me a steroid cream and started feeling better. Iv used it for 2 weeks now but still have new bumps that pop up. Their apparently doing bloodwork Tuesday to test my liver and bio acids which I guess can cause PUPPS? Has any other moms experienced this? If anything comes back positive I was told depending on what it was they might choose to induce me? Making me kind of anxious hearing this information. Did any moms come back positive? If so was baby okay?
