My sister in law

My sister in law has been married to my husbands brother for three years now. She already has a 2 year old and a 1 year old is is pregnant again. She has had a baby every year she has been married. I don't even have one kid yet! I just got married a few months ago and I feel like she doesn't want me to have any of the spot light. They said they were done having kids and now I just got married and now she is pregnant and has all the attention again.
