Help Make My Rainbow Baby Wish Come True

My name is Victoria. I am 26 years old. When I was 17 I got pregnant with my first born son. He was diagnosed with Hypoplastic left heart syndrome at 20 weeks pregnant. I was diagnosed with high blood pressure, preeclampsia and gestational diabetes while pregnant. My don died 8 hours after he was born on August 27, 2013. I have been on different types of birth control since then due to severe bad periods and cramps. I talked to my obgyn and they said due to my periods and bleeding i should get pregnant now or have a hysterectomy. I toke out my birth control at the beginning of december to prepare to have a baby.
