Ridiculous maternity benefits

So discovery has a maternity benefit that only covers 2 scans... Which gynecologist did you guys consult with that only does 2 scans for a 9month pregnancy? How does that even make sense? So now I have to pay cash for my scans for 7 months since I do not have specialist benefits. I have 3 dependants who has not used any of theirs so am I not able to transfer over! It just makes me so furious that after all these years paying and I have no other way with this medical aid.
