to feel bad even though its not my fault?

[biddysmama]

my bil and sil have been trying for a baby for 4 years.. ive had 2 babies in that time and i'm 11 weeks pregnant with another

im not looking forward to telling them :(

Ooh heck. I wouldnt look forward to that either. We've got a similar situation with a family member who has just lost theirs at 20 weeks, we're at 8 weeks

You have no reason to feel bad, and congratulations :)

As long as you let your bil & sil know that you are not oblivious of hard it must be for them to hear the news, I am sure they will be happy for you.
