Baby on the way?????

Sally • My names sally. Mummy to my beautiful 2yo Isabella.😍😘 2nd baby due July 2016
I'm 34+4 and just went to do my usual wee before bed. I noticed there was white stringy stuff in my wee. I've now just laid down in bed to go sleep and got a period type cramping across the bottom of my belly and my bottom of my back :( is this all normal or is she getting ready to meet us? Any advice appreciated xx
