16 weeks preggy - transvaginal or pelvic ultrasound?

Hello mommies, 16 wks preggy here. i was supposed to have transvaginal ultrasound before quarantine. but since delikado and di makalabas, di natuloy ultrasound ko. pag ba nagpaultrasound ako after the quarantine, transv pa din or pwedeng pelvic na? last tvs ko kasi was during 6wks pa lang ako. thank you!
