Okay I'm due on Thursday..and this morning I woke up at 4.30 with the most horrid lower tummy pain..which was period like and lasted about 30 odd sec and then stopped. It was sore as it woke me up, but nothing to bad. So I went back to sleep..
Then at 7.18 I woke up screaming in pain
..it was like nothing I've even felt before, right across my whole lower body and I felt very sick. It was really quite heinous pain really deep. The main pain pasted after about 30 / 40 secs however my back still ached for a good 2 mins afterwards. And then relief, thank god as it was extremely unpleasant!
I'm feeling fine..and had nothing since! 
Now I'm sure I might be grabbing at straws, but is this things getting started, what the heck is happening!
Any advice would be great, haven't been feeling myself for a few days, but hey I'm nearly 40 weeks who does at this stage..
