Ignore your doctor.
A Novorapid only regime will give you a huge rollercoaster of blood sugars.
It's going to go sky high when you don't eat, and bottom out when you do.
Switching from Lantus is one thing, but completely cutting out long term is absolutely, stupidly dangerous.
There have been studies on the safety of Lantus during pregnancy, and it doesn't increase the risk of anything.

My daughter was born at 38 weeks, 6lb8. 16 m/o now and a terror lol. I was on Lantus all the way through, and no problems, apart from nausea :S
I think if you are doing fine on Lantus now, there's no need to throw another complication in when there is no cause.
We know that bad sugar, especially during the first three months, can be very detrimental.
Lantus hasn't had a huge scale trial to prove it's safe, but there is no reason to suspect it's not.
So i'd stick with the Lantus. But honestly, your doctor has absolutely no idea what he's on about.
You CANNOT sustain a steady glucose with just novorapid at meal times.
That will be dangerous.
