Hi Anna.cb,

I'm so sorry to read about your diagnosis. Hopefully someone will come along here to give advice who has been through this while pregnant, but just wanted to let you know of the charity 'mummy's star' who specifically offer support (and a forum) for those with cancer in and around pregnancy. The 'Breastcancer now' website also have a 'someone like me' service where they can put you in touch with someone who has also been in your position who may be able to offer some guidance. 
 

For general chat about BC there are many of us going through or been through it here, so do still ask for support/ any questions here too if needed. You are also entitled to a second opinion throughout your treatment if you want it. Wishing you all the best.
