Rhogam leaked after administration

At my appt yesterday I got tdap, a blood draw and rhogam. The tech doing it seemed slightly inexperienced now looking back. She couldn’t get my blood to draw and called in for her superior to do it, nbd. But then when getting rhogam, she pulled the needle out and some dripped down my arm. She didn’t say anything, didn’t seem concerned or anything so I let it go. But now the next day, I’m stressing a bit. I’m rh- so I know how important it is, and I’m hating myself for not questioning her when it happened. Was her lack of concern from inexperience or because she truly knew it was fine? Anyone have knowledge on this or even have it happen? My next appointment is in 2 weeks so if anything I find myself protected enough to wait to bring it up and see the doctors opinion on the matter. But make this a lesson, always always speak up 😔
