well lots of women discharge alot more when they are pregnant not always at the beginning, and it could just be the way the baby is sitting he might just be in the wrong place and it can be painful , when i was pregnant with my daughter she us to put her feel up under neither my ribs and stretched out until it hurt to the point that i was in tears, do be surprised if it's just the way the baby is laying. but if it doesn't go away which it should and your still worried then call ask him what you should do.
