Do you have watery discharge too?

I have watery discharge 4-6 time a day. it makes a round of 2 cm in my panties. I have had that for 2 weeks maybe. Im worried it can be amiotic fluid... I called the maternity dept and they told me to walk half an hour and to see if I continue to have watery discharge and if it leaks more... If not its only watery diacharge. Should I go get check even if I walked 40 minutes and my panties were not slippy at all? 36 weeks tomorrow...and so tired to not know whats happening with my body!
