It is very unlikely that the fillers will have any effect on your pregnancy. You don't say what type of filler you had, but many are made of a product our bodies produce and break down naturally. The fillers are also localized to your face, they do not travel to the rest of your body.
Hello, and thanks for your question. Please do not stress over this, as it is extremely unlikely to have caused any harm. I do, however, recommend waiting until you are no longer pregnant or breastfeeding before having additional procedures done. Best of luck, Dr. Frucht.
