I have the same thing - totally grosses me out when it does come out, cause sometimes it seems to be running down my leg... Ewww!
Pantie liners are the best answer for that - they're awesome at keeping you (and your legs

) clean. Even though the feeling of having a wet pantie liner is kinda gross as well, its just a lot better then feelin it drippin down your leg.
Have fun concieving - and lots of baby dust 2 u!
Good luck!
