Possible excessive discharge?

So for quite some time now, I've been experiencing what seems like excessive discharge. It's clear and watery and/or translucent white. Occasionally it's enough to soak through to make a damp spot on my pants but that doesn't usually happen. I've been tested for a wide range of STDs that all came back negative. It's not super heavy all the time but it's especially bad right now. I'm also just coming off my pill (microgestin) my period is frequently irregular...if that makes it worse haha. I'm so scared my doctor is going to tell me there's something wrong with me that'll ruin my relationship with my boyfriend. Please help if you can...hopefully I'm overreacting
