My right side hasn't produced anything today and I'm freaking out. DD has been nursing on it with a shield great for 2 weeks. Last night she started nursing on it for 30 minutes and then dozing off. I normally see milk dropping out of it but haven't seen anything today. She has been nursing on it and then crying 10 mins later from hunger. I pumped after and barely got a few drops from it when I normally get .5-1oz from it. I have no idea what is going on and am freaking out. Any idea what is going on and how do I fix this??????
