Accidentally ate half portion of medium well steak,when it supposd to be welldone.is it safe for my baby??Im so worried.

Hi, I’m 28 weeks pregnant now. Today I went to a restaurant and ordered well done steak. After ate it half portion, I realized that the steak was slightly pale pink ( I guess it’s medium well ) in the middle. I didn’t realized earlier cuz it covered with gravy and I stopped eating it. Now I’m worried so much that it may affect my baby... Can someone tell me if it is fine or not? Thank you ...
