My mum was the same, every twinge you have she would run round like a mad head thinking i was starting labour
Have things progressed any yet?
When my waters went i was say on the setee, Luckily leather and i just looked down and found myself sat in a puddle- didn't even know it had come out- then when i stood up more came out and my sanitary towel was soaked though every 5 min, plus i started with contractions about 10 mins after.
Everyone is different
