Any advice ?!?!?

As a woman at the age of 17 I thought about having kids. I got my birth control out September 2017. I’ve made the decision to start ttc and 6 months later it happened. April 31 2018 was the happiest day of my life I was so happy and my boyfriend was happy...I told certain people but the world found out and everyone was happy for us. We went to 2 appointments before we found out the news and before that we had a perfect healthy child. I was having some cramps but I wasn’t bleeding or nothing so I thought it was just normal I was busting my ass off at work and honestly doing stuff that i shouldn’t have been doing. Then our third appointment I was 11 weeks right our the edge of the “safe zone “ I found out there was no heart beat and the baby stopped growing... I cried for days and till this day I still can’t explain the feeling .. it’s been more then a year and im still waiting for my little blessing. It so hurtful seeing anymore pregnant or with a child cause that could of be me .. but god bless them cause who knows what there journey was . I finally made an appointment to get checked but I think if I find out if I can’t have kids I’m literally gonna get so upset.....
