Help?!

My boyfriend was on steriods like a little over a year ago then he stopped taking them for us to try to conceive and we actually did conceive 3 months later but ended in miscarriage. My first time being pregnant. Can him having a history of steroid use cause any problems with our fetus in anyway? He is completely off of them and will remain off of them we are going to be trying again within the next 5 months from now. ?!! I just want a happy healthy baby.
