I am in the middle of my 2nd month of taking microgestin. I started having a weird sweet smelling, light colored, and somewhat cloudy urine in early December. My discharge is regular. It's a semi clear and white sticky lotion like looking discharge. I finally started taking an antibiotic, I think it's called backstrom(sp), this morning. I plan on taking it twice a day for 3 days.. How long should it be until I can be sexually active without the antibiotics effecting my birth control?
