Husband with high prolactin

Hi all, I hope some of you can give me some insight. We've just found out my husband has elevated prolactin levels due to some medication he has to take (not very high, just 'elevated'). We are repeating the blood test in a month to double check this before looking into other options. My question is: is it safe for us to still ttc in the meantime? We conceived in February - this unfortunately ended in a miscarriage. My concern is that if we conceive again while he has high prolactin it may cause an abnormal embryo? If anyone can shed light on this I'd really appreciate it - has anyone conceived while either themselves or their other halfs have had high prolactin and it's been fine? Many thanks in advance!
