Let's face it - there's the pregnancy symptoms which everyone knows (and asks you about) like morning sickness, swollen feet, cravings, stretch marks etc.
But what pregnancy symptoms / side effects have surprised you??
For me I'd say...
Skin tags - wtf are they all about? I must have had about 5 new ones since getting pregnant - two of which are on my neck and although tiny I feel them daily when moisturising.
Snoring - my DH reliably informs me that I snore (loudly) most nights. He's too scared nice to wake me up or prod me though but has acquired a variety of nicknames for me like Mrs Snorey-Head! Sometimes I even get the odd snore while awake which is embarrassing 
Dribbling - I dribble a lot more in my sleep that I ever used to...maybe this is because of the snoring though?? I am basically really gross to sleep next too!
So what's your surprising symptoms?
