Took Advil while pregnant on accident

Jenna

This is my first pregnancy so I’m just now learning a bunch of things. I heard it was okay to take Advil while pregnant, I’m 12 weeks I’ve been taking it for my headaches maybe once a week. I did not know until I looked it up to make sure it was okay and I found it wasn’t do you think it will harm my baby? I didn’t take it frequently
