4d ultrasound

Veronica • George Alek Jr 4/08/17💙 Layla Jae 8/16/2018💜 Currently pregnant due in November
I have it scheduled for this Thursday at 10:45am to find out the gender and I will be 15 weeks and 2 days when I go. But I'm having on and off morning sickness. At my last ultrasound made a big deal that I didn't eat a big enough breakfast so baby wasn't that active on the ultrasound. So any tips or suggestions. I'll make sure to take nausea the night before and really try my best to eat something that morning but anything else I should do?I really hope the tech don't have no problem showing me the gender .
