33weeks with Twins

Ebony
Really really suffering now.. Constant Braxton hicks, everything is aching and I can't bring myself to walk more than a metre at a time! The babies move so much that I am not enjoying it at the moment! No sleep cause of constant moving and it's not just little movements they take my breathe away! I have been scared about labour up until this point I now cannot wait!! I'm hoping for a natural birth with an epidural which is recommended incase twin 2 turns breech during birth. I am told that I could go into labour at anytime due to having twins, my last scan 2 weeks ago showed twin 1 was estimated 3lb13 and twin 2 4lb5 so pretty good weights! Does anyone have any sure signs of labour?? I really wish I could have an insight on what it will feel like before it happens!
