Unprotected sex with a new partner, he ejaculated less than 2 min. his semen was kinda whitish yellow, 5 days later had light yellow pus discharge with little odor , no pain coming from my vagina?

It isn't clear from your question whether you or your partner is currently having pus-like discharge. Either way, an STD is a good possibility, especially gonorrhea. You both need to be checked out right away. Good luck.

Not sure what you are asking - if you are asking if you are pregnant do a pregnancy test and if you are asking if you have a STD - do a STD test.

Please have a complete evaluation by a Gynecologist and advise your partner to have an evaluation with a Urologist to find the cause of the problem and recommend treatment.
