Period sex

Hey so last night me and my boyfriend were having sex. I gave him oral and we kissed before we noticed I had my period. He didn’t have blood on his face or anything and We’ve both been tested in the past but I was just wondering if he’ll like get sick or something. Like I stated before we’ve both been tested negative for hiv/aids etc so I’m not worried about that. I guess I just wanna know will we be ok🤦🏽‍♀️
