Still trying after 12 years.

My husband and I have been trying to get pregnant for over 12 years. A few years ago we just have up. On Dec 31, 2016 I found out I was pregnant and did everything know to man to protect her. But in March my water broke and on 4/1 I gave birth to her but she only lived for 3 min. Now we are trying again but I'm scared and I'm already 36 almost 37. Just not sure if this is a good idea anymore.
