leaking amniotic fluid?

Jessika • ♥️ 30 year old mommy to 4 sweet babies 3 on earth and one in heaven (born sleeping at 31 weeks 6 days)
I believe I may be leaking amniotic fluid! 
I'm just shy of 27 weeks now
I'm not sure exactly how to tell at this point. I have tried to put liners on to see but I have a bad cough. 
Cough plus pregnancy isn't a great mix because I can't always make it to the bathroom!
Any ways I can tell ? 
Or should I just wait until the next Drs apt?
