Doctors made mistake with gender

Hi all, I'm 25 wks 3 days went to my doctor today for an ultrasound because the measurement that the doctor got was not matching the weeks that I have. So I went in and the ultrasound tech measured the head and body of my baby. She stated everything was matching my weeks and so I asked simple question because I already knew I was having a baby girl based on my 18 weeks ultrasound, I asked could you please confirm the gender, to my surprise she said if I was told the sex of the baby and if it was at the same office also by whom. Yes to all the questions then she asked if it was her that did the ultrasound I said no again I asked is it a girl she answered with I'm sorry its a boy. I bought the crib, clothes and her theme princess castle with pink, I have a lot to return. My baby is a blessing and what's god will I accept. Material stuff I could return or giveaway. Thank you Lord my baby is doing great and growing strong.
