Pregnancy and discharge

Cameron
I'm 16 weeks and 5 days. About 2 days ago I noticed after I whipped that I had discharge that was kind of clear but had a yellowish tint to it. No smell at all. It's not in globs, It looks gooey But I didn't touch it. This is gross but it looked kind of like a booger.Every time I've whipped since then I've been checking the toilet paper. I've had it happen about 4 times in the past 2 days. idk if I should be worried ??! When should I call my doctor ?? I have no other symptoms
