Gender Appt?

I have my NT screening set for next week and scheduled a gender scan at the ultrasound place we went to with my daughter to find out gender early. They were so great, highly recommended and accurate! However I was 16 weeks with my daughter and I calculated wrong this time (don’t know where my head was at!)

I will only be 13.6 weeks at the time I made the appt. they said they still can tell but I’m wondering if I should reschedule. I’m torn so would love to know what you think! ☺️
