whos fault is it when a girl gets pregent before marraige

Well I got pregnant twice before I was married and both my kids are loved. I am still with my partner and we are very much in love. Being married does not affect the way you parent we are both brilliant parents. It was noones fault with the first pregnancy we wasnt using contreception, which was silly but we have a beautiful daughter now, with our second daughter we was using contrecetion but I still fell pregnant, its an act of god and a miracle that we have 2 beautiful daughters its nobodys fault. Before you ask we will be getting married soon when we can afford it not because we have children but because we have a loving relationship and we want to!
