Just drink a lot of water Thâts what I did I was 19+6 when I found out that I was having a healthy baby boy :)
Hope everything goes well hun
ive heard rinking alot of water can help see the baby bettter and yes they can determine the sex at 19 weeks since they found out that i was having a boy at 16 weeks :)
Drink orange juice the acid makes the baby uncomfortable and active so that they can catch a glimpse of the babies stuff
