Excessive amounts of discharge?!

Is anyone else suffering from excessive amount of discharge?? I feel just so damp there as it can be quite watery... I always get paranoid about fluid leaking but I've been tested twice and came back negative.. TMI but I do my own test where I wipe onto a black cloth and if it comes up white I know it's just discharge.. I'm 25+3 does anyone have any tips.. I wear liner.. do you think the kind of nickers and pants increase discharge??
