I am planning to do that and this is the brochure that I’ve gotten from TMC - https://www.thomsonmedical.com/wp-content/uploads/2020/05/Brochure-3D4D-Ultrasound-Scan.pdf The suggested timeline for TMC is to do it between 24-32 weeks. I’m going to schedule one this Friday during my gynae check and can probably tell you the cost after that.
