Yay Stu Congratulations to you both on your BFP hunny (big fat positive). I bet you are so excited but the worry is also understandable for anyone especially with a 1st when you are unsure what to expect.
Firstly don't expect to much from the docs, They usually just confirm the preg then book you with a midwife who does all the info.
Best thing to do is to try not to worry about things that could go wrong etc & concentrate on the good bits, If anything happens then you deal with that at that time. Help your partner rest when she needs it, Don't treat her like she is disabled as this does wind us women up, be a little more sensitive if she feels tired & ill that's all for now i guess really until she starts to get a proper bump.
Worrying is only natural, If there is anything in particular you are worried about just ask on here everyone is great, There is even a dads bit if you want to talk to them too.
Congrats again & wishing you all the best with your new addition to be xxx
