As Neils Bohr showed, it is possible for electrons to move between energy levels. Light contains energy. If a photon of light strikes an atom, it is possible for the energy in the light ray to be transferred to one of the low energy electrons moving around the atomic center.
Spotting before a period is due â reasons for spotting before a period can be implantation, from a cyst or a short luteal phase and impaired egg quality. Spotting in between cycles â this is a difficult term to answer but often means your cycles are growing shorter; often with perimenopause.
But because of the timing, many women interpret the spotting as a very light and early period and donât consider themselves to be pregnant. An implantation bleed is different to a period because there is less bleeding and it usually appears as a pink or brownish discharge rather than a blood flow. It does not increase in volume and does not involve the passing of clots.
