ohhh girls my heart goes out to you. This is also my first pregnancy and i know exactly how u feel.
Take in these good weeks where u dont feel anything coz u will want them later on!! I didnt believe i was pregnant either until my first u/s at 12 weeks. i went in there totally expecting to see nothing on the screen. There was tho U are both so early yet so u wont be feeling too much. I didnt chuck even once. Dont worry the sore breasts will come with time and when it does get here u will feel like u have jinxed urself coz it isnt the most pleasent thing in the world lol.
So my advice to you is... relax.... take this time out to spoil urself...get a massage or something. Believe it or not u are both a step closer to being a mummy every hour that passes..

good luck and take care xoxo
