When do you generally get your first scan?!

Sharni • Married my best friend on 5 October 2013. Lost our first baby 15/01/2015 at 19w2d.LGH now due with 🌈
So I went to the doctors to confirm because I couldn't believe my eyes (8postive tests). She confirmed my pregnancy and then I was rescheduled for 4 weeks time. My question is when would be the lolly hood of getting my first scan?? Thank you ✨??
