I had today a small watery discharge happen. It was very small, only happened once today and otherwise I have not noticed any 'leaking' or any other discharge. I don't have any pains in my abdomen, but I experienced some cramps, they weren't bad and only lasted a few moments and happened while I was at the store shopping and I haven't experienced any more or anything else. I am 16 weeks and 5 days, this is my first baby, is this something to be worried about? I see my OBGYN tomorrow afternoon and will request an ultrasound and tell them, I'm curious as to anyone else in my position or who has been that can offer and comfort or advice for me ?
