Ob-Gyn questions? Ask a gynecologist online.
Hi there. If you only had a single encounter and used a condom, your chances of having picked up an STD is very low. If you are also on the pill and have been taking it regularly, your chances of being pregnant are virtually nil. So while I would consider it very unlikely that your current discharge is sexually related, it makes sense to get tested just for the reassurance alone. If it is BV, this can easily be treated with metronidazole cream or pills.
