I just pumped for 20 minutes and what came out of my left side looked like cloudy water. The right side looked like normal milk, but not the left side. What is going on? The weather is warm, but I don't think my milk should be that clear. Yesterday LO spit up what looked like pure water and she had a very watery poop, so this doesn't appear to be an isolated incident. HELP! How can I fix it?
