No yolk sac

Hi moms, went for transvaginal scan just now and dr couldn’t see yolk sac only gestational sac. Gave me progesterone and going in 2 weeks again to hopefully hear heartbeat 🙏🏽 based on LMP I should be 6 weeks today but I ovulated late so according to ovulation I’m 5 weeks 4 days. Anyone else with me?
