Irritable AF... Baby soon?

Jessica • Mummy to 26 month old Alice... Number 2 due April 2019 👶🏼
Hi ladies, I'm 37+6 and have been very lucky with my pregnancy....
But this week I have felt like extremely severe PMS - that furious anger / could burst into tears at any given moment feeling. And reacting completely out of proportion to any situation!
I've also become very spotty which is a change from the rest of the pregnancy. 
I definitely feel like my hormone profile has changed - but my question is - do you think labour is coming soon?
