Rhogam question.

I am O- blood type and had to receive rhogam because my husband is positive.

I thought I’m not supposed to receive blood besides anyone but my own?

Rhogam is made with human blood, I believe type A.

What’s your opinion..? Did anyone have complications after receiving this shot?

I’m pregnant again so I’m going to need to receive it again but I’m just scared to keep letting that into my body.
