Having a very excitable panic as I don't know what's happening. I'm 40+8, first baby. Haven't had any real signs of labour til this. Had achy back pain and a few stabby stomach pains today. Have also had lots of clear watery discharge recently.
So I'm laid in bed just now on my side. Suddenly feel trickling wetness from my vagina. Go to bathroom and sit on toilet, small amount of liquid leaks out and into toilet, smells awful, kind of like semen. 
Then realise I also need to wee so do that. It's possible more liquid came out while weeing but no idea! Then, TMI sorry, unsure as to why, a load of air comes out from my vagina in a loud fart noise. How delightful.
That was about ten minutes ago. Nothing since.
What happened!?
