Can frequent scan be harmful to my baby?

Assalam and hi. I am currently 21 weeks and about to go for my detail scan this saturday. Tapi my mother in law and sister in law suruh tangguh for a month sebab last week Selasa i baru appointment di Klinik Kesihatan dan ada scan baby. And the following day i slipped and went to the emergency and was scan another 3 times to make sure theres no bleeding and baby ok. So last week i scan a total of 4 times. Tapi kejap2 je scan tak lama. So is it safe for me to go for detail scan this saturday? Mother in law and sister in law kata kesian baby kena tekan2. Hope my post is not too long and ada respons from mommies out there ?Thank u
