TMI! Just had a BIG bloody show

39 weeks and 3 days today. Woke up from bed and had a gush. I panicked and underwear is soaked with bloody mucus and a lot of it. Threw underwear in bin. Trouser slightly soaked as well. Called midwife and she said to put pad on and if waters leak then come straight in. She just said baby is getting ready.

What do I do now? Walk? Do those exercises? I have mild cramping going on now and cant bend anymore as bump feels super sensitive and heavy. Btw been having somewhat painful BH for over a week that radiates to my back.

Many thanks xxx
