Cold-eez while pregnant

So, I'm almost 19 weeks, and I'm starting to get sick (mucus-y, scratchy throat, sneezing/coughing a lot). For the past few years, whenever I've gotten sick, I've taken Cold-eez cough drops. This evening, I grabbed one and took it without thinking. it didn't occur to me that maybe I shouldn't take it until it was almost gone. I've only taken the one. Seeing as how it's almost midnight, and I can't call my doctor, I started Googling. The company website says "talk to your Healthcare professional", and WebMD says don't take more than 2 or 3 a day. I'm not really planning to take another, but I was just wondering if anyone else has asked thier doctor/ob, and what thier responses were. Planning to call my Dr Monday and see what she suggests. Thanks!
