I don’t know what to do

My husband and I have been trying ttc for almost 2 years with not really any luck. I got pregnant a month after we started trying but unfortunately I lost it and have been able to conceive again. I’m just really confused I had no trouble conceiving my daughter (she’s almost 7). I did get Mirena put in after I had her, and I had it for 5 years... I think it’s probably time to make a doctor’s appointment, what would the next step be? My doctor did mention after my miscarriage if I did conceive again that I would need to be put on progesterone? Would it still be low after almost 2 years of not having birth control?
