As far as I know it was nothing but I would talk to your doctor tomorrow. I know I did end up having a urinary
infection and a
yeast infection sometime after seeing the discharge because I never told anybody.
Here's what it says in my pregnancy book:
If the discharge becomes a yellow-green, develops a stronger smell, or your vulva, vagina, and anal region become reddened and painful, particularly when you urinate, tell your prenatal caregivers.
