That does seem insensitive.
Speak to her, and say to her that you cannot get over her bringing that up with you at this time.
I do not think she understands what is going on with your life. This is really something she should have kept to herself, or spoken to another friend about.
My sister in law has been ttc for over a year, and now I am pregnant and am really worrying how this will make her feel. It is something your friend should really have thought about.
Some issues are very sensitive, and in this case it is something that she should have been thought about deeply before announcing to you. She sounds very thoughtless and inconsiderate.Definitely speak to her.
I am so sorry for the frustrations you must be feeling, and I hope your turn is just around the corner.
Take care and g.l
