Normal Vaginal Bleeding

Uterus Vaginal Bleeding

Normal vaginal bleeding is the periodic, bloody discharge from a woman’s uterus during menstruation. It is also known as menorrhea and is characterized by cyclic hormonal changes.

The ovaries in every woman produces an egg, each month, which travels through the fallopian tube and reaches the uterus. If the egg meets a sperm fertilization occurs and an embryo is formed. Otherwise the egg, along with the inner lining of the uterus, breaks down and bleeding occurs through the vagina.

The ovaries also produces hormones which controls the development of female body characteristics and regulate the menstrual cycle.

Menarche is when menstruation first begins in a girl and menopause is when menstruation stops in middle age.

Normally menstrual bleeding lasts for 3 to 5 days and  during this phase a woman loses about 40 ml of blood and 35 ml of serous fluid. Initially the discharge is bloody but after a couple of days it is more watery or lightly blood stained. The normal range of blood loss varies between 2 to 16 tea-spoonfuls or from 10 to 80 mls. It is due to this monthly blood loss that women are more susceptible to iron deficiency anemia with  low hemoglobin. This is more common among vegetarians

I am a 39 year old female. In my early to mid 20's I never bled from intercourse and my lover as very well-endowed. Intercourse never hurt and was very pleasurable and never bled during sex ever nor did I bleed after. Now at age 39 I have a new lover who is very well-endowed, but I have heavy bleeding during and after intercourse. I have no pain and no discomfort at all. Intercourse with my new lover is amazing and wonderful. So I ask, why am I having this bleeding during and after intercourse? I do have a history in these last 10 years of uterine fibroids in which I had a uterine ablation done 8 years ago. And I have always suffered from very heavy, painful, clotty mensus cycles. I have a GYN appt next month. Could my fibroid issue be a factor now at age 39?
