i dont think it is possible but i thought i knew too,
infact i was right, 4 days after sex,
and i texted dp to say, i think i am pregnant and this time it is a boy,
i was right, i was pg and he was a boy,
the last time i didnt know i was until a week or so after the sex, but i did dream in that week that i was handed a baby girl,
i was laying in a bed and it took me a while to realise she was mine for keeps (we lost all our 3 previous p/gs)
i was so sure of my dream, i had dp on my left side and i saw my mum come though the door to meet her first grandchild over my right shoulder,
it was all correct
the funny thing was, at a private scan we were told she was a boy, i was totally amazed as i remembered my dream,
at the 20 weeks scan they said a girl,
i bloody knew i was right...
good luck x
