12 weeks gender scan

Deyondra

So today i went to see baby. She was calm at first but when the tech started probing ๐Ÿ˜‚๐Ÿ˜‚ she just went ballistic ๐Ÿ˜. But anyway doctor said Iโ€™m measuring 1 week ahead and even tried to change my due date. She asked me if i wanted to know the gender of course i said yeah... she said itโ€™s a girl but donโ€™t quote her. I didnโ€™t see a penis and being the mom of 4 boys i know what it looks like. So my question is could she really tel this early?
