Leak in amniotic sac?

I’m 31 weeks today. Anyone ever had a leak in their amniotic sac before? I hope this is just a false alarm , but I had warm fluid leak out and It was clear, and I can’t be sure if it’s regular vaginal fluid or from the sac? No cramping or anything... just want to be sure because I don’t want leave to the drs for a false alarm. I threw a pad on to give me 30 minutes minimum to see if I leak anything else..
