Please don't behave like an insane person who had put seeds into his Farm and then he used to dig the ground every day to see why the plants are not growing . You have to give time for everything.

Are you a Radiologist who has his own Ultrasound Machine and does TVS for his wife every day? Please have patience and behave like a mature person.

Rather than CNS it's the weeks of pregnancy that is important
