Miscarriage and now ttc

I'm not sure exactly how to word this so it doesn't sound so bad. I was in a 4 relationship from 15-19, with a not so good person. Was on bc, had to take antibiotics, then ended up extremely sick and had to be taken to the ER. I don't remember much. But, found out I was 1-2 weeks pregnant. At 17 years old. I was terrified. I ended up having a miscarriage about 3 weeks later. And at the time, I was kind of relieved. Being 17 and with a not so good person. But now, here I am almost 25 and married to an amazing person, and we've been trying for nearly 2 years to get pregnant. So it makes me really honestly upset about the miscarriage even though it happened so long go. I'm more upset about it now than I was then. I'm not sure if that's normal. I feel bad because I'm upset about it now. Sorry so long. Just didn't know where else to turn to. My hubby doesn't really understand it.
