What are the holes in the top right?

Jennifer • Hopelessly in love with my soulmate, mother of four beautiful kiddos: 💕03/03/08, 💙05/06/10, 👼💙09/28/18 - 06/02/2020, 💙03/27/2022 and current expecting #5 in July

I haven't seen anybody else's look like this the doc didn't say anything and I only noticed after my appointment when reviewing the photos. Anyone have any insight? 5 weeks 6 days.
