Lots Of Discharge

Hi everyone, just for some background SO and I are ttc, this month is our first cycle that we have tried. I am 4dpo and have had some short, infrequent cramping in my lower right abdomen. The biggest thing I've noticed is all this discharge. It's a whitish clear and VERY watery and has no odor. I don't have discharge very often and it is so abundant it is making my underwear wet. I know I'm probably being overly observant, but has anyone else experienced this before BFP?
