Is anyone experiencing wet discharges??

I am currently 17 weeks and since the first trimester, I have been getting a lot of discharge. The wet and not cheese like kind. For any given day, it will be so wet that it seeps through to my pants. I need to start using pantiliners now. It is also smelly like the after sex smell if you know what I mean. Is anyone else experiencing this? Also, I am still using Summer's Eve feminine wash. The doc says ok but want to see what you ladies think as well.
