Top 10 Flat, Brown / Tan Rash Causes

  1. 1.Normal Case of Spotting

    Spotting is vaginal bleeding that occurs between periods. Many women experience spotting between periods and it is often nothing to worry about. Oral contraceptives (the pill) can cause spotting as a side effect, especially if they have a low estrogen dose, someone started on them recently or does not take them on the same time everyday. Additionally, hormone supplements that only contain estrogen (often used in menopause) can cause spotting as well.

    You most likely have nothing to worry about. If you take the pill, try to take it at the same time every day. If the spotting becomes severe or is bothersome, you should speak with your primary care physician or OBGYN.
