anxiety and mind filled with too many thoughts

A little over year ago my husband had started trying to have kids. I became pregnant in June and on July 7th I miscarriaged. I sit here today knowing more then I did last year but still not pregnant again. In October I found out I was anemic. I was put on meds to help and it's been 7 months and I'm still anemic. I am still so tired all the time. Idk what to do... I take the meds they are giving me and Geritol every day. I've lost weight and stopped stressing so much. I'm almost 27 and i worry that something is still wrong that the doctors aren't telling me or not testing for.... what questions should I be asking if I'm still not well cus idk what to do anymore 😔😔I've made an appointment for later this month
