3 times in a row after intercourse with my husband I go to the bathroom to urinate and when I wipe there s light red blood. But, it s only on the tissue and I do not bleed out. I ve called my gynecologist and he doesn t seem too concerned but I ll still probably see him. About a month ago I did have a vaginal ultrasound that was normal. In the meantime I m going out of my mind with worry. I m a young 28 year old mother to a healthy 19 month old son. Any ideas what could cause this?
