Expert answer:
Your main problem should be depression or anxiety. Psychological illnesses usually choose an organ (target organ, different for each person) to relay some of the psychological pain and relieve internal tension, turning it into physical symptoms, such as in your case vaginal bleeding. You need to treat your nervousness and it will probably improve from the physical. In some cases this is mere coincidence (unlikely) and you have both (psychological problem and physical problem in the womb). You need to find a gynecologist.
