I am due for my period next Friday, but usually do not show many symptoms except for acne (which clears up with my face wash/skin care). But my acne has only been getting worse. The last three days I have been getting nauseous after I eat, but this morning I almost puked while riding in a car and had to have the ac blowing in my face. I have also been having mild tenderness on the tops of my breasts, and cramping of my lower abdomen. Lastly, I had a dream two nights ago that I took a pregnancy test and it was positive, so I took one the next morning when I got up and it was negative. Should I take another one? And what is your recommended brand?
