Benadryl and pregnant?

I have some sort of reaction on my face little bumps on my face around my eyes, forehead, cheeks. No swelling anywhere thank God but is it safe to take Benadryl or even maybe Benadryl cream? This is my 4th baby and my dr never said if it was safe or not so I’m not sure also I’m 15 weeks is it safe to take and has any other mamas taken it before this early in pregnancy?
