5 week scan ?

I see a lot a woman get a ultrasound at 5 weeks my ob wants to wait till 7 , I have had an ectopic and I’m scared of another. They took two hcg blood draws and they doubled but that does not rule out an ectopic completely. With my ectopic I was in bad pain at by 6 weeks and now I feel like I’m just waiting for something really bad to happen when they could just give me a US at 5 weeks and avoid possibly losing my only tube.

Should I push harder for a 5 week US just to make sure it’s growing in the right place?
