I had sex (condom & bc)2days after my period, a week later i had white discharge but at one point it was a lot and thick, clumpy? am i pregnant?

Have evaluated...: Although it is unlikely that you are pregnant if you are on birth control and you used a condom, it is possible and a pregnancy test will help you determine that. I would see your gynecologist about the discharge - they can evaluate for infection (yeast infection/STD) that could be leading to the discharge and treat you appropriately.
