Discharge

Okay I know the only true way to tell your pregnant is by taking a test but I'm still 7 days away but I went to go to the bathroom and I had like a big glob of whitish thick discharge,my boobs are also sore and when I went to pick my daughter up today and was holding her she was kinda sitting on my stomach and I felt short of breath and like she was laying right on sometbibg. I know sounds crazy! But has anyone else had these symptoms and turned out pregnant?.
