Today i found our mutual close friend is pregnant! (Second child)They have been ttc for about same time as us. I am happy but at the same time its like wth? Also a coworker of us (we work same place) told us she is pregnant a few days ago. I also have a friend that is expecting her 3rd child as well. Im starting to get frustrated and kinda deppressed. I dont know what to do. Am i getting too obsessed? Have you TTC felt the same? Please help!
