OB SONOLOGIST

Ive already went to 3 different OB SONO pero wala silang ultrasound sa clinic nila, kailangan pa sa ultrasound ng mismong hospital which is mas mahal and sa ibang araw nanaman, tapos babalik again for reading means another consultation fee!!! can anyone recommend me a good OB SONO na may ultrasound na sa clinic nya? Thank you so much!!
