Doctor concerned about development...

So, I’m 11 week and 3 days with my second baby. My first is 15 months and has been 100% healthy from the very beginning, never had any problems during my pregnancy at all. On Tuesday, I had my first ultrasound and I was exactly 11 weeks. After the u/s my doctor pulled me and my boyfriend into her office to talk to us and told us she was concerned that the babies skull and brain are not developing correctly. She’s having me wait 2 weeks and then go back for another ultrasound at the hospital. She told me if what she saw is correct that there’s “options”...

I am SO stressed out about this which of course is putting a ton of stress on the baby. Has anyone else ever had this happened and everything turned out okay?! Need something to calm me down and ease my mind a bit in the mean time...
