early labour signs?!

Before anyone went in labour did anything they feel really sick and exhausted? I went to sleep around 4am because I wasn't tired and then woke up at 6:30 am with cramps like I needed the 'toilet' but it wasn't that,they was more uncomfortable and my back was aching,then I managed to get back to sleep but the cramps kept waking me up,today they've eased and they are not painful where I cannot handle them I just feel exhausted and sick? I've been for a nap,had a nice warm bath and stuff..did anyone else feel like this or? I'm a ftm so I don't know what early stages are or feel like.. I'm due the 10th..
