Take aviane when wake up (same time or w/n 2 hours max), sex w/o condom didn't finish, 10 days later white watery thin discharge. normal? concerns?

Two concerns : It sounds like there are two things that could be weighing on your mind. First, could you be pregnant. Answer yes, and if you miss your cycle, a pregnancy test should be done. Preejaculatory fluid can contain sperm as well as transmit infection which is your other concern. If you have concerns about STDs, get tested. A family doc is ideally suited to help with this. Consider making an appointment.
