Low placenta & 2 white spots on baby’s liver @ anatomy scan

Louise

Did anyone else have any of these? And are they anything to be worried about?

I’m 20 weeks and they explained the placenta is currently covering the entrance (Cervix) & that they’ve noticed two white spots on baby’s liver which could mean an infection, so I will be having further tests & scans.. but are these serious? / Has anyone else experienced either of these before?

Hope it’s nothing to worry about?☹️😩
