Loosing hope

Me and my hubby got pregnant in March of 2017, in may , we had a miscarriage. Was / still heartbroken but they said it was nothing we did . I miscarriaged naturally with no help and after the fact they said I look healthy to try again as they seen nothing was wrong . We’ve been trying ever since and nothing has happened . What should I do ? Is it us ? We do drink on the weekends so I’m not sure if that could be a reason. I know I’m young ( I’m almost 21 and my hubby is 21 already ) but I’ve been taken care of kids literally since I was 10. All my friends have kids and kids are my whole life . Also, I had cancer as a kid so they told me I will go through early menopause ( most go through it late 40’s but for me they say in my 30’s) so I need to have babies ASAP. What can I do
