Hello, and I hope I can help you today. Pregnancy symptoms vary widely between women, and many of the same symptoms we commonly associate with pregnancy such as nausea, bloating, breast tenderness, headaches and irregular bleeding can also happen from an irregular menstrual cycle as well as pregnancy. Furthermore, modern urine pregnancy tests are extremely accurate and become positive even 10 days after conception, so if your tests are negative, you are not pregnant. So the most likely reason you are having a small amount of bleeding is that you are going to get your menstrual cycle soon. If your period was late, you may bleed more or less than usual depending on the hormonal cause for the delay in your cycle. Women can have irregular periods for a number or reasons, including weight gain or loss, travel, stress (including the stress of worrying about pregnancy) as well as medical conditions like diabetes and thyroid disease. If you to have unpredictable menstrual cycles for more than 3 months, you should have a hormonal evaluation by your physician. But in most cases, once you do get your period, your cycle will most likely return to normal the following month. I hope I was able to adequately answer your question today and that my advice was helpful. Best wishes, Dr. Brown
