Am I in labour?

Hi ladies...

Just looking for some advice. Around 10.30 last night (UK time) I got this awful wave of nausea and sort of a constant stomach pain which also went around my sides. This lasted around an hour or so. I finally managed to fall asleep and was woke up by an intense cramping (almost like when your bursting for a poo pain, sorry tmi🙈) I almost felt winded as it took my breath away. This lasted a minute or so but came back every one to two hours. I wasn’t in agony with it but it was enough to keep me awake and I couldn’t sleep through them. Is this labour or the start of labour? I am full term. Thank you ☺️
