Paid for a private scan this weekend as not having my nhs scan until 14 weeks

Paid for a private scan this weekend as not having my nhs scan until I’m 14 week I’m currently 12w2d And I’m feeling so impatient 😩 especially as i have a subchronic haemorrhage which was seen on a private scan at 9w4d (although I haven’t had any bleeding) hoping that’s a good thing and that it will be gone

My question is do I need a full bladder for my 12w4d scan ? Thanks in advance x
