17 weeks and....

Ok so this may be a little weird but I have either been uncontrollably peeing myself or I’m leaking. I have had to change my underwear I couldn’t tell you how many times over the last 3 days for clear liquid just coming out in large amounts. At first I honestly thought I was sweating because it is so hot here but it’s not sweat. It happened at the baseball fields today while we were watching my nephew and I was sitting down. I called into the on call and she didn’t seem concerned but how are they to know over the phone anyway 🤷🏻‍♀️ Is there a way to clearly distinguish amniotic fluid vs urine? No smell whatsoever. This is my 3rd pregnancy and I’ve never had this with any of the others.
