Ok I m a 26 y/o F, and I recently started taking a low dose birth control the day my period ended which was 8/24 I started bleeding lightly on day 3 of starting the birth control, as each day passes I experience pregnancy symptoms, the breast tenderness, the metallic taste in my mouth, nausea especially with different odors. The problem is I am not pregnant as test were done to rule that out. The bleeding with all these symptoms gets heavier with each passing day, cramps associated with that too. I need to know what exactly could be causing my discomfort and all these odd sign and symptoms I m experiencing?
