Ambiguous genitalia

I had an ultrasound done at 13 weeks and was told I was having a girl. Come 20 week ultra sound I am told they may be seeing both genders. The child may be ambiguous genitalia.

This is obviously scary for me and my family not knowing what the future holds. We were told to get blood work done to see the gender and possibly chromosome issues. We are still waiting for results. Two week wait is loaded with a lot of stress and anxiety.

Has anyone experience anything like this? How did you proceed after birth?

Please help and advise is anyway possible. I greatly appreciate the help.
