its probably just the sperm from your partner discharging from your body.

Sperm would not be discharging from you 2 days after you had sex. Most women have some form of discharge through out the month. Unless it is very thinck, has a strange/foul odor, or is accompanied by itching, then I would say that its just normal. If you want to be sure you can purchase the Vagisil at home test kit which will measure vaginal pH levels indicating the likelihood of an infection.
