GrowFins i think your post may have got lost amongst all the food chat food is 100% taking over our lives! Congratulations! I wouldn't worry too much about the drugs from the op, hopefully it was all too early for them to be of any sort of a problem but at least your midwife can give you some reassurance at your booking appointment! It's my first too, and although it was planned, i keep getting waves of omg what have i let myself in for 🙈🙈
Leighding your feelings sound totally normal (although that doesn't make them any more fun for you)! Blame the massive increase in hormones, general worry of early pregnancy, and exhaustion on top of it all and you're allowed to feel sad, stressed and anxious. Have you told your OH or anyone close to you how you're feeling? Take some time to look after yourself and have a pamper and i hope you're feeling better soon! 
Loving all the food chat today! Been out with a close friend and her 1yo daughter today and got to talk pregnancy A LOT as i told her pretty early on! She got me a pack of Rich tea as soon as i walked in the door which was a godsend!! Still obsessed with strawberry nesquick, and gingerbread men atm!
As for telling my mum and dad, we've been planning for a while! My mum wrote a kid's book ages ago for fun so my OH is going to illustrate it and then the last page will say something like: This book belongs to Baby surname due Dec 2017.
Not sure i can wait another 5 weeks to share the news!!
