after period discharge

So this isn't exactly a bloody topic but I didn't know where else to put it lol
There are times where I have like A LOT of discharge.. like in the morning sometimes, when gravity hits and I walk to the bathroom it runs down my leg.. Fucking gross right!? I need panty-liners even when I'm not bleeding kind of thing.. the doc thinks it strange but also normal.. 
Anyone have probs like this or some insight as to why it's so much more at times?
