Possible: The yolk sac is usually present by the fifth week of pregnancy - it would be concerning if there was no yolk sac seen during the fifth week.

At 5 weeks 2 days transvaginal ultrasound only saw gestational sac after ivf. Should the yolk sac be visible by that time?

Generally: The yolk sac is seen when the mean gestational sac diameter is 8mm and a heartbeat at 16mm. You can get the dimensions of the sac from the ultrasound technologist. Best of luck.
