Im so confused on when baby can actually hear us. The other app I use told me a few days ago baby was able to hear me when I talk. Now today this is saying baby can hear me and others. When I googled it most things say after 20 weeks. Has anyone talked to their doctor about this yet? I'm interested to know what is true. I don't go for another appointment for another week..
