Start of labour??

Bit long winded, not sure if I'm reading into it all. So last night about 9pm I had back ache smack bang in the middle of my back, nothing too severe. Then I woke up a few times in the middle of the night with achy legs, and frequent toilet trips. About 5am I started getting period pains, managed to sleep through these until 7.30am. Now I'm up and definitely period pains!!! Is this early labour???
