So I'm a mom to four amazing kids 12,10,6,3  and I'm having crazy baby fever and I'm feeling like I really want to try for another baby but I'm so scared after my last one which was my hardest pregnancy .i have 3 boys then my princess and I'd love to have another girl so bad so she can have a sister and can use my daughters baby clothes again . 
Help!!
