Feeling frusterated (venting a little)

Im just trying to vent..... I'm begining to get frustrated because when i got pregnant with my previous 2 babies it was quick and easy and now me and my husband have been trying for baby #3 for 8 months and nothing... I really am happy for all you ladies who are pregnant but is it wrong that at times i kind of feel a little angry about it... My husband thinks i should just delete the app but i really enjoy reading all of your guys question because i can relate to some of them
