I would go for it. As a FTM, I wanted to go for 3D/4D but my husband didn’t want to hence we didn’t go for it. I kind of regretted (cause first baby right) and partly because my 2D was bad, didn’t see anything at the later stage anymore…. Just black scans. (Gynae is good but machine is old)
If you want, just go for it. This one once over, no chance already. 🥹
