I am a 30 years old, i just had a tvs and the result shows that i have multiple hypoechoic masses seen within, withe different measurement,m1 is 22mmx17mm, M2is 16mmx12mm,M3 is 16mmx9mm,M4 is 8mmx7mm(intramural). before this test i have had two preterm labour. could this be the reason for the miscarriages?
