So I'm on the birth control Lutera (been on it for almost a year) and also on antibiotics because I found out I had strep a little over a week ago. And this period was very light compared to my others there was not 1 heavy day or blood clots and normaly i have about 2 or 3 with clots. Well yesterday was suppose to be my 7th day and today I have white, a little watery vaginal discharge with very light pink colored blood. Could that be from the anti-biotics or should I see my doctor. I had it yesterday and today so maybe I should wait I'm not to sure.... any one know what I should do? Or what it is?
