Hormonal changes: Menstrual periods are induced by a series of hormonal changes that occur over the course of a month (usually), but these hormonal fluctuations can cause symptoms of bloating, breast tenderness, nausea, fluid retention(they are called moliminal symptoms, and are very normal). The non-specific symptoms of pregnancy can be mimicked by a lot of things. It is possible that you had a miscarriage-butunk.
