I am 24 years old and both me and my husband have decided to delay our first child until my husband gets settled in his job properly. One of my friends told me to use vaginal diaphragm for birth control. I have no clue about this thing as I have never used it in my life before. So, I want the people to inform me as to how effective is diaphragm for birth control? Anybody using it previously who would like to share her experience with the product!
