Gushing fluid

Katie • 31, married, blessed with a baby boy 💙👶🏼💙 01/09/16 Irregular cycles 35 days+
My DH and I had BD last night and this morning I suddenly started gushing fluid. I had to change my underwear. It happened again about two hours later when I was sat down. 
​The fluid is clear like water and doesn't smell of anything. 
Has anyone ever had this and do you know what it is?
​This is our second month of trying for our first baby. I'm on CD 27. I've taken an ovulation test and it is a BFN
​Would love to know people's thoughts. Thanks
