Pelvic pressure..

Beth • 20🙋🏼 - engaged 💍 - ballet & dance 👯 - pregnant with my first 👶🏼 - my baby boy is due 10/02/2016 👣💙
I'm 39+1 and other day my midwife said I was 2cm and his head was very low down, I have really bad back ache/pain and today I've felt a lot of pressure down there like he's going to drop out can hurt sometimes when I move about like period type, any advice ladies??
