Within the last 4 months I have experienced very light vaginal bleeding the day after I drink alcohol. I first noticed this symptom after a night of heavy drinking. The bleeding was moderate and had stopped after 30 minuted or so. I got my period a week later. This has happened several times since, but the bleeding has just been a slight discharge and has never been as significant as the first time. Last night I had about 4 glasses of wine and yet again, there was a slight blood-like discharge. I just finished my period last week. I m 21 years old, 125 pounds and 5 4 . Also, on most mornings after I drink, I take an ibuprofen.
