Little signs

This morning I woke up at 4am (fairly standard for me nowadays) but decided that everything needed cleaning. I even cleaned the cooker and oven. Everytime I bend over or stand up or move in general since I woke up I need to wee. I had a gut instinct that something was going to happen today and then I lost some of my mucus plug. Now I know that things like mucus means nothing but I'm nearly 40 weeks and hadn't as yet lost any at all. Also I have this weird feeling like when you are coming on your period before the cramps come and there's a weird achy heavy feeling. I'm hoping that all these weird little signs mean something might actually be happening!!!
