Hi. I Was Wondering Is There A Chance That I

Hi. I was wondering is there a chance that I can't have children? Reason I ask is because when I was 15 I got pregnant and had an abortion and now I'm 24 and trying to convenience with my fiance and it hasn't been working. I also have server anemia but currently my iron levels are up. We been trying for over a year now and starting to give up hope. I have normal monthly periods. With no server pain. So not sure what's going on
