Ugh, typos! LOL! Ignore my typos. I seriously type faster than I think.
Anytime you have unprotected sex you can be pregnancy. You should take the pregnancy test when your next period is due.
If you are having discharge right now, about 2 weeks after your period and about 2 weeks before your next then you are most likely ovulating. Which means you can conceive (it is when the egg is released from the ovary, ready for fertilization). However taking the test now won't be conclusive. You'll need to take the test about two weeks after the sex encounter which should be when your next period is due.
Good luck!
