Asthma medication safe?

Hi. I just found out I'm pregnant. Haven't had my first appointment yet but the excitement and my allergies have my asthma irritated. I feel like I may need my inhaler if it gets any worse but I don't know if it's safe. My inhaler is xopenex. If anyone knows the answer please let me know ASAP. Thanks in advance
