I didn't have any a week before other than dropping, then even more so on due date.
I had no tell tale signs on my due date (12th), but on my nephews birthday (14th) I was having twinges on the bus journey to MIL's, then felt heavy all day. Came home in a 4x4 and I was having sharp pains and strong twinges along the way. I knew I'd go into labour at some point that night. I was on my ball as soon as I got home, went for a long walk through park with OH at 10pm, then came home to DTD (literally forced OH lol). 4am (15th) my labour started and had her at 11:14pm (16th). Exhausting labour.
