Hi. Is There Any Ob-gyne Online That I Could Chat

Hi. Is there any ob-gyne online that I could chat with? I need a serious consultation in regards to my wife. Her last menstruation was on Dec. 29, 2015 up to Jan.02, 2016 (5days). What is the safe days for having sexual intercourse for this month of January? We had a sexual intercourse yesterday (Jan. 19,2016). I have use the pull out method and I am sure of it because by the time I pulled it out, I do masturbate a little then before it came. Does precum can lead to pregnancy? I have urinated a lot already before Jan. 19, 2016. I hope you could help me with my concern.
